Impossible Celebrities has revealed its line up of all star line up of names.
The BBC One game show will taking to primetime for the specials, continuing tonight (August 25) at 7PM.
It follows three successful series of the Impossible quiz show on daytime.
Hosted by Rick Edwards and produced by Mighty Productions for BBC ONE, !mpossible Celebrities will see 18 celebrity contestants begin their !mpossible journey and compete across six-episodes to give themselves a chance of winning £10,000 for a charity of their choice.
In each episode, the celebrities must avoid giving !mpossible answers as they battle it out across three rounds of !mpossible style multiple choice questions. Every right answer takes them a step closer to a shot at that jackpot - but a single !mpossible answer will knock them out for that episode.
