VINCE VAUGHN

The Wedding Crashers star claims he has picked up useful parenting tips from British child expert Jo Frost's programme, and puts them into practice when he babysits his three nieces and nephew.

He says, "You watch the show, these kids are terrors. They're hopped up, they've been eating candy. The nanny comes in. Naughty step, boundaries, everyone hugs each other, the chauffeur drives her away. It's an amazing thing."
