X Factor rejects reunited: Kitty Brucknell and co return to perform charity single

Some have been gone from our screens for so long we've almost forgotten them, while some it seems like they never left.

But last night, all the X Factor finalists - bar shamed Frankie Cocozza of course - returned to the studio to perform the show's charity single.

Kitty Brucknell, Sophie Habibis and Two Shoes led the wannabe pop stars who joined the current semi-finalists, One Direction and JLS for a rendition of Wishing On A Star.

It wasn't just another chance for them to show their vocal ability on live TV again, it was also a reunion for them to catch up with their former housemates.

Although previously admitting clashing with Misha B because they were 'both ambitious', Kitty Brucknell showed her support for the Mancunian teenager during the sing-off with Janet Devlin.

She tweeted: 'Yeah... OK Misha B isn't going anywhere!!!'

But it looks like she is championing Little Mix to win the show, adding: 'OMG crying!!! Little Mix I love you! I knew you could do it.'

Brucknell, 27, clearly enjoyed being back on stage: 'So much funnnnn!'

Craig Colton, who left the show just a week ago, was also been showing his support for bookies' favourite Little Mix and fellow Scouser Marcus Collins.
