Celebrities join Big Brother fun

Graham Norton, Lauren Laverne, Mina Anwar and Tara Palmer-Tomkinson will be live outside the Big Brother house tonight.

They will be telling Dermot O'Leary which housemate they are backing to win, in a special edition of Big Brother's Little Brother on E4 at 7pm.

All of the evicted housemates will be reunited, before the winner is announced.

Liberty X will also be live in the studio to perform Just A Little Bit, which has become the housemates' anthem.
