The acts won places in this weekend's Wembley final of the ITV1 show last night. Lily's mentor Kelly Rowland saw her second semi-finalist Misha B leave the competition.
Arriving at the BBC studios in Central London this morning, the finalists were all smiles as they prepared to speak to breakfast DJ Chris Moyles.
The acts will all visit their respective hometowns for special gigs during the week, with Little Mix performing in Romford later today.
The X Factor final will be staged in front of 10,000 fans at Wembley Arena this weekend. Coldplay, Leona Lewis, JLS and One Direction will be among the special guests to appear.
