Nicolo Festa

Her rendition of "One" in the first live show brought her rave comments, including Cowell saying: "I am amazed that we overlooked you in this competition. I didn't like what you're wearing, but honestly that's not an issue, because by a far mile, that was the best vocal for the entire competition thus far". Cohen went on to sing "Purple Rain" in the second week, progressing on to the third week, when she sang "Whole Lotta Love". Cohen landed in the final showdown with John Adeleye, but was able to progress onto the fourth week after her performance of "One Night Only" convinced the judges to keep her in the competition. However, voting statistics revealed that Adeleye received more votes than Cohen meaning if the result went to deadlock, Adeleye would’ve been saved. Cohen then went on to sing "Relight My Fire" and got through to the fifth week. On week 5, Cohen sang "I Don't Want to Miss a Thing". Cohen was once again in the bottom two, against Katie Waissel, and sang "Un-Break My Heart". Cowell voted first and voted to save Waissel. Cheryl Cole who was asked to vote second, refused to send home either act because she mentored both Cohen and Waissel. However after she decided to abstain, she later asked to vote last to send the result to deadlock, the majority of votes was used. Only Minogue was in Cohen’s favour but Walsh voted to save Waissel and finished tenth overall. After the series ended, it was revealed that Cohen received more votes than Waissel, meaning if Cole had been allowed to send the result to deadlock, Cohen would have been saved.

In week 1 of the live shows, she sang "We Are the Champions". She was put in the bottom three as a result of the public vote, but because Nicolo Festa polled the fewest votes, Waissel had to sing in the final showdown with F.Y.D., the other bottom three acts from week 1. She sang "Don't Let Me Down" in the final showdown and was saved from elimination by the judges by a majority vote, with only Cowell (F.Y.D.'s mentor) voting against her and Cole, Minogue and Walsh voted to save Waissel. Voting statistics revealed that that F.Y.D. received more votes than Waissel meaning if Walsh sent the result to deadlock, F.Y.D. would’ve been saved. In the second week of the live shows, Katie sang "I'd Rather Go Blind". She managed to avoid the bottom three this week and secured a place to the third week, where she sang "I Wan'na Be Like You". In the fourth week, she sang "Bewitched" and was in the final showdown with Belle Amie. Waissel was saved after the result went to deadlock and Belle Amie were eliminated. She was in the final showdown again the next week after performing "Don't Speak", but was saved by a majority vote over Treyc Cohen when Cole refused to vote against either acts of hers but wanted to vote last to send the result to deadlock but wasn’t allowed to. Cowell and Walsh voted to eliminate Cohen and only Minogue voted to eliminate Waissel. Voting statistics revealed that Cohen received more votes than Waissel meaning if Cole was allowed to send the result to deadlock, Cohen would’ve been saved.

They all applied as solo candidates to the competition, but failed to qualify in the Girls category. The judges, after a suggestion by Cowell, put them together in a band, qualifying them for the Groups category. Their qualifying song, as well as their first song ever as a group, was an acoustic version of "Faith". In the first week of live shows, they sang "Airplanes" by B.o.B and were safe. On the second week of live shows, they sang "You Really Got Me". As a result of the public vote, they were put in bottom three and had to sing in the final showdown on 17 October, after Storm Lee polled the fewest votes and was eliminated. They sang "Big Girls Don't Cry" and were saved by all other three judges. Walsh, Minogue, and Cole voted to save them and eliminate Diva Fever, leaving no need for their mentor Cowell to vote. Voting statistics revealed that Diva Fever received more votes than Belle Amie which meant that if the result went to deadlock, Diva Fever would’ve been saved. In the third week, they sang "I'll Stand by You", in which they progressed to the fourth week, where they performed "Venus". However, they ended up in the bottom two with Katie Waissel, and sang "Breakaway" in the final showdown. After the vote went to deadlock, Belle Amie had the fewest public votes and were eliminated.

Diva Fever is a duo consisting of Craig Saggers, 21, and Josef Al-Smadi, 26. Saggers, from Longthorpe, Peterborough, is studying English Language and has recently completed his second year. Al-Smadi, from Wigston, Leicestershire is studying English through the Open University while working for British Gas in Leicester. Saggers has previously performed in his home town of Peterborough at Fireworks and Christmas Lights events and won an X Factor style contest called the Top Notch Factor. Josef was in a Leicester four piece boy band called "Horizon". They initially auditioned with "Let It Be" until Simon asked them to change it after expecting them to be "more interesting". Saggers said "I’m singing for my life, because I ain't having a 'no'." and they then performed "Proud Mary" and received three yeses. At bootcamp, they decided to apply facepaint to stand out and sang "Bad Romance". At the judges' house, they performed "Love Machine" but weren't picked to be in the initial top 12 acts. However, a wildcard option was introduced for this year's show and Simon Cowell chose them as his wildcard act for the live shows.

John Adeleye, 30–31, is a care worker and award-winning songwriter from Harlesden, London and had an artistic career under the stage name J'Nay. He was a founding member of the band Nu-park, with fellow musician Shad. The band was further expanded to become a 5-piece band by including Mylz (Tyga), Raheem and Anton Gordon. and a solo artist after the break-up of the group. In 2008, J'Nay released his EP Merry Go Round containing 5 tracks.

At her first audition, she sang "I (Who Have Nothing)" and at the judges' houses, she performed "Fix You", though she forgot the words to the song. Her employer, Tesco Ireland, started a campaign for all staff to support her. Before the first live show, Byrne suffered a throat infection and the show's bosses asked her to quit smoking to avoid making the infection worse. She performed "It's a Man's Man's Man's World" in the first week, "You Don't Have to Say You Love Me" in week 2, and "I Who Have Nothing" in week 3 – the song she had sung in her audition. In the quarter-final, she performed "All I Want Is You" and "Brass in Pocket" and was in the bottom three with Katie Waissel and Wagner. After Waissel received the fewest public votes and was eliminated, Byrne was in the Final Showdown with Wagner. She was sent through to the semi-final by judges, Louis Walsh, Dannii Minogue and Cheryl Cole. This meant Simon Cowell did not have to vote but confirmed that he would have also sent Byrne through to the semi-final. In the semi-final, she performed "Never Can Say Goodbye" and "The Way We Were" and was in the bottom two with Cher Lloyd. She sang "It's a Man's Man's Man's World" as her sing-off song but was eliminated with only her mentor, Walsh voting to send Byrne through to the final, finishing in fifth place. However Byrne had received more votes than Lloyd meaning if there wasn't a final showdown or if Minogue or Cowell voted to send Byrne through to the final or if the result went to deadlock, Byrne would have advanced to the final and Lloyd would have been eliminated.

During his time on the show, it was revealed that Wagner was presently a UK incapacity benefit claimant, based on his frozen shoulder. After his elimination, Work and Pensions Secretary Iain Duncan Smith commented on Sky News to Adam Boulton: "One of the people who was working on his case, I understand this, I don't know precisely, noticed [Wagner] was managing to leap in the air with his arms held above him when I am told that he had a frozen shoulder and frozen shoulders tend to mean that you can't have your arm in the air; it's impossible and therefore he was off work. I suspect he will find he will be asked to come in and explain himself as to why he was on benefits in the first place. If you don't mind me saying so, [Wagner's case] illustrates the biggest problem we have got, which is incapacity benefit has grown like mad." However, it was revealed that Wagner was telling the truth and kept the DWP informed as he appeared on the show only 6 months after his second shoulder surgery – he is no longer on incapacity benefit.

In July 2013, Campbell and Wardman found two members: Jessica Batist and Clarissa "Risa" White. The new formed girl group are in thoughts of maybe adding a fifth member. Dodient Records have since taken Belle Amie off the label. The girls are now looking to find a new firm that can take the newly formed Belle Amie to success. "Girls Up" was re-recorded with Batist and White's voices, and their debut album as a new group will be entitled Fresh Girl.

In week 1 of the live shows, they performed "Sunny". However, Josef was stuck down with Laryngitis and lost his voice, so Craig was forced to sing the entire song. They made it through and were safe. In week 2, they sang "Gotta Go Home" / "Barbra Streisand". In the song, they made tributes not only to Barbra Streisand, as in the original, but also to Judy Garland and to judge Louis Walsh, in addition to shouting their own name as well. As a result of the public vote, they were put in Bottom Three and had to sing in a showdown with another of Cowell's acts, girl group Belle Amie. After singing "I Will Survive", they were eliminated by the judges vote 3–0, with Walsh, Dannii Minogue, and Cheryl Cole voting to eliminating Diva Fever. Cowell, didn't have to vote after all the independent judges eliminated Diva Fever in favour of saving Belle Amie. Minogue based her vote on the performance of both bands on the final showdown, whereas Walsh said he based his vote on who he thought had the greater potential to grow in the coming weeks. Cole decided to eliminate Diva Fever, and Diva Fever finished 13th overall. Simon Cowell apologised to the boys for letting them down and Josef retaliated by saying, "You need to make it up to us Cowell". When the voting statistics were released after the show, it revealed that Belle Amie received fewer votes than Diva Fever meaning if the result went to deadlock, Diva Fever would have been saved.

Since their appearance on season seven of the X Factor, Diva Fever have been invited back twice to perform live at Wembley alongside other memorable acts. In 2013, they returned for the live final performing mashup of memorable songs alongside Jedward, Wagner, Rylan, Kitty Brucknell, Johnny Robinson, and Two Shoes. In the 2014 final, they also returned as part of the X Factor 10 year celebration performing alongside Wagner, Chico, Stevie Ritchie, Chloe Jasmine and Katie Waissell; they performed The Black Eyed Peas' hit The Time "Dirty Bit". Diva Fever entered dressed all in silver accompanied by four dancers on dog leashes in a very S&M inspired entrance.

For their qualifying song in the judges' houses, they sang "Beggin'". In week 1, they sang "Billionaire", adding a reference to Cowell in the lyrics. As a result of the public vote, they were classified as Bottom Three and had to have a sing-off showdown with Katie Waissel, also a bottom three contestant. They sang "Don't Stop the Music". After the judges' votes, they were eliminated by a vote of 3–1 with all three judges Cole, Minogue and Walsh voting them out. Only F.Y.D's own mentor Cowell voted in their favour. They finished 15th place overall. After the series ended, voting statistics revealed that they had received more votes than Waissel meaning if Walsh sent the vote to deadlock, F.Y.D. would have been saved.

At the judges houses Fiuza-Carrilho performed "You Got The Love", to which Walsh joked to his assistant judge Sharon Osbourne that "He fancies you". Although he was not picked to be one the initial top 12 acts, mentor Walsh chose him as his wildcard for the live finals. Wagner moved out of The X Factor house after the second live show after complaining about his fellow contestants' behaviour. It has been speculated that he been regularly sniffing "Raid" aerosol cans, attributed not to an addiction, but a severe bout of psychosis that made him believe there were ants in his skull.
