X Factor 2012 judge Tulisa Contostavlos took to the stage herself tonight, performing new song Sight Of You.
The N-Dubz singer was originally due to perform last weekend, but delayed her performance to coincide with the release of he album.
Speaking about her performance recently, Tulisa said: “I’m doing a song on the show – it will be a ballad.”
Tulisa was seen performing in a grey hoody and black leather jacket as she borrowed one of Union J's boxes to stand on for the song.
Talking to Dermot afterwards about going from judge to performer, Tulisa said: "You enjoy it but it's terrifying."
Tulisa’s solo career has got off to a mixed start, with her first solo single Young hitting number one back in May.
But her follow up Live It Up, struggled to crack the Top Ten.
Sight of You and Tulisa's album, The Female Boss, are out this week.
