We love an insight into our fave stars lives, but this show's going to give us far more than we thought we'd find out as the kids can't be prepped, and as we all know, children could say anything!
Ex-EastEnders star Nina Wadia and her six-year old son Aidan, actor Will Mellor and his five-year old Renee, and singer Jamelia and her daughter Tiani, who's seven.
What embarrassing secrets and cringeworthy info will come to light when the kids are quizzed? Will the parents be left red faced? And who will walk away with money for charity and a Big Star's Little Star trophy?
Big Star's Little Star, ITV, 8pm
