Chris Rock's mother disrupts his comedy shows every time she is in the audience - because the funnyman is too scared to swear in front of her.
Rosalie Rock imposed a strict ban on swear words as the star was growing up and his childhood fears of letting slip a rude word are still strong, even as an adult.
And now whenever Rock knows his mother is watching from the crowd, he would rather change his gags - which are usually peppered with obscenities - rather than offend his mum.
Rosalie tells New York Gossip Column PageSix, "I cramped his style. (Later) he was never told where I would be seated."
