Fresh from releasing his brand new biography, with a little help from his mum, Caspar's faced the wrath of Roman's #CelebrityLieDetector test!
And things might have just got a tad awkward thanks to all sorts of questions, such as, "Did you do anything last night that you wouldn't want your mum to know about?"
Plus not one to shy away from the fun, Caspar's mum herself even weighed in with big hitters like, "Who do you prefer, me or your sister?" And "Have you ever stolen from me?"
