Teddy Sinclair

In early 2016, Sinclair started a band, Cruel Youth, with (her husband) Moon. Their first song, "Mr. Watson", was released on Soundcloud in February, followed by "Diamond Days" in April, which was also released on iTunes. Their third single, "Hatefuck", was released in early September, along with the release of their debut EP, +30mg, on 16 September 2016.

On 14 September 2012, Sinclair unveiled the video for "Controversy" to start promotion of her second studio album, Trouble. The album was centered on her troubled childhood. Sinclair attended an after-party for the 2013 MTV Video Music Awards, held on 25 August 2013 in Brooklyn, New York City, where she performed various songs from Trouble. Two days later, "Outta Time" was released as the album's second promotional recording free of charge in a Polydor Records newsletter, coinciding with the US release of Trouble. Trouble was officially released on 3 September 2013 as a digital download in the United States and Canada.

As Natalia Kills, Sinclair released the studio albums Perfectionist (2011) and Trouble (2013). In 2014, she married fellow singer Willy Moon. The following year, the couple served as judges on the second season of the New Zealand version of The X Factor, but after the season's first live show, they were fired after their controversial remarks towards a contestant. As of July 2015, she now goes by and performs under her legal name Teddy Sinclair. In 2016, she started a three piece girl band, Cruel Youth, with whom she has released the EP, +30mg (2016).

Sinclair adopted the stage name Natalia Kills from the interjection "you killed it!", after her record company advised her that her legal name, "Natalia Cappuccini", was "indescribable." Kills released her debut album Perfectionist in Germany in April 2011 following the release of her first single, "Mirrors", which hit the German Top 10. The album was described as a concept album by Sinclair, claiming that everybody is a perfectionist. The album was accompanied by four singles, "Mirrors", "Wonderland", "Free" and "Kill My Boyfriend". Through 2010 and 2011 Sinclair opened for Kelis, Robyn, Kesha, Katy Perry and the Black Eyed Peas over various tours. Sinclair was featured in LMFAO's single, "Champagne Showers," and in Junior Caldera's single "Lights Out (Go Crazy)".

Her biggest commercial singles were the BVMI gold-certified singles "Mirrors" (2010), "Free" with Will.i.am, and the UK-top 40 hit, "Champagne Showers" with American pop duo LMFAO. She has additionally written songs for Angel Haze, Madonna, and Rihanna.

In 2007, while writing music for films, she posted Womannequin, a demo she produced and wrote under the name Natalia Cappuccini, to MySpace. The EP received 2 million plays on the website, and she reached the top of the unsigned artists chart. During this time, using the name Verse, she also co-wrote and appeared on "They Talk Shit About Me" by French recording artist M. Pokora and met Guillaume Doubet, who would go on to direct many of her videos, in Paris. Sinclair moved to Los Angeles in 2008. Arriving without money or a place to live, Sinclair "lived out of these motels, bumming around, trying to work with or make songs with anyone who would have me for a couple of hours in the studio". At the time she says she did awful things adding "I was just trying to survive and I was too young to know better." While in L.A., a DJ introduced her to Will.i.am after hearing her demo and learning that she did not have a record deal. In January 2009, Will.i.am signed her to his record label, Will.i.am Music Group. "We had a really good creative chemistry," she said in a 2011 Billboard interview.

She began pursuing a music career and had a significant breakthrough as "Candy Rapper" in 2003, when she won a BBC Radio 1 MC Battle in Leeds. She signed to the UK record company Adventures in Music and released her first single "Don't Play Nice" under the name Verbalicious in February 2005. Sinclair told W that her childhood nickname from her mother was "Verbal" because she talked and sang a lot. She adopted the name and variations of it as her stage name at some points during her career.

Teddy Natalia Noemi Sinclair (née Cappuccini; born 15 August 1986), is a Grammy-nominated English singer, songwriter, producer and actress. She has recorded music under various aliases including most famously Natalia Kills and Verbalicious. She is currently the lead vocalist of the band Cruel Youth and her own musical project, The Powder Room.

Sinclair has mentioned Kate Bush and Alanis Morissette as her most important musical influences, describing them as emotional artists "who write honestly about their opinions and experiences." The singer also stated she considered Gwen Stefani, who is a musical and stylistic inspiration, as her "hero", adding that Prince, Vanity 6, and Freddie Mercury have already inspired her during live performances. Sinclair explores music that is both confessional and bold when looking for inspiration, she reveals: "I don't listen to music to let go, I listen to dive in", listing Hole, Marilyn Manson, and Eminem among her favorite artists and bands with whom she grew up. According to Jon O'Brien of AllMusic, Sinclair gradually composed a musical tone incorporating "the theatrical dance-pop of Lady Gaga, 1940s film noir, and the electro-gloom of Depeche Mode." She also reported that she has always been a pop music fan, especially in evoking contemporary "new age" artists as Adele, Lana Del Rey, Marina and the Diamonds, Ivy Levan and Lorde.
