Markus Feehily

He announced on social media that he and Shane Filan Co-write the new single for Emeli Sandé and Ronan Keating called "One of a Kind" released on 2020.

In October 2018, a video was posted to Westlife's official social media platforms announcing the group's reunion as a four-piece. In 2019, the group will be headlining "The 20 Tour," named in honour of Westlife's 20th anniversary since its formation and the release of its first single, "Swear It Again," in 1999. In addition to touring, Westlife will also be releasing new music. "Hello My Love," the first single from the group's upcoming album, will debut on the Graham Norton Show on 10 and 11 January 2019.

On 22 February 2019, he announced his engagement through his Instagram account, during holidays on Hurawalhi in the Maldives.

On 3 October, Mark Feehily and his fiancé Cailean O’Neill announced the birth of their daughter Layla via surrogate.

As well as releasing music as part of Westlife, Feehily has also released music as a solo artist, under the name "Markus Feehily" rather than "Mark Feehily," which he was known as in Westlife. In February 2015, Feehily launched his solo career with a radio premiere of his debut single "Love Is a Drug" on RTÉ 2fm in Ireland. The next day the track premiered online, via Wonderland Magazine. Moments after the premiere of the song, it was made available for pre-order on iTunes, with the official video for the track launching on his Vevo channel two weeks later. The song was released on 19 April 2015. He released his debut solo studio album Fire on 16 October 2015. It includes the singles "Love Is a Drug" and "Butterfly." He was a support act for Wet Wet Wet and Mariah Carey. He was also invited by Russell Crowe at Olympia Theatre, Dublin, October 1, 2017 for his "Dublin Indoor Garden Party gig" to sing "Love Was My Alibi," written by Crowe and Carl Falk for the film "The Water Diviner," which Crowe both directed and starred in, accompanied by Alan Doyle and Falk. His second album Christmas, featuring the track "River," a rendition of the song by Joni Mitchell, was released on 1 December 2017.

During the interview with The Sun, Feehily also announced his romantic relationship with British fashion photographer Kevin McDaid, a member of the now-defunct British boy band V. The pair, who lived together, had been dating since January 2005 after having met at a Cheerios Childline Concert in Ireland. Feehily said that while he did not intend on getting married right away, he was happy to know he could form a civil partnership in Britain with the recent passing of the Civil Partnership Act. In December 2007, Feehily and Kevin appeared on the cover of Attitude. The couple became engaged in February 2010. On 31 December 2011, Feehily announced via his Twitter account that the couple had split up.

Feehily is interested in charity works and supports the charity group Aware. He was shortlisted in 2011 as one of the top 50 most influential gay individuals. He congratulated his local football club Sligo Rovers on its victory in the 2011 FAI Cup Final.

In August 2005, he publicly revealed he was gay during an interview with the British tabloid The Sun. Feehily had recognised his sexual orientation when he was 14 or 15 years old. His family, bandmates and close friends knew his sexual orientation. Westlife's manager Louis Walsh, however, was unaware of Feehily's sexual orientation when he began managing the group. As the only gay member in Westlife, Feehily had kept his sexual orientation private. Unlike his bandmates, Feehily did not discuss his private life in interviews, although he had dated women prior to his coming out. In yet another interview, he told The Sydney Morning Herald that despite the fact that the majority of Westlife's fans are female, there had really been no negative reaction.

Feehily rose to fame as one of the two lead vocalists of the boy band Westlife, the other being Shane Filan. Before Westlife, Feehily, Filan and Kian Egan were members of the self-formed, six-piece, Sligo-based boy band IOYOU, previously named Six As One, which released the single "Together Girl Forever" and songs "Everlasting Love" and "Good Thing." Louis Walsh, the manager of Boyzone, was contacted by Filan's mother and came to know about the group. The final line-up, established on 3 July 1998, consisted of Feehily, Filan, and Egan from the original line-up, and Nicky Byrne and Bryan McFadden, new members who auditioned from Dublin. Boyzone singer Ronan Keating was brought in to co-manage the group with Walsh, assuming an advisory role.
