Big Star's Bigger Star sees three celebrities come on with one of their parents, either their Mum or their Dad. They compete over three rounds which all reveal funny, cringe-worthy, or even salacious secrets about the celebrity.
First show features Adam Thomas, Frankie Bridge and Joel Dommett. The winning pair get the chance to play for £15,000 for their chosen charity.
Coronation Street's Kym Marsh, McFly's Harry Judd and Simon Webbe from boyband Blue compete for the 15,000 pound jackpot.
