Ashton Kutcher says he's given up punking his co-stars. The 'That 70s Show' star, who produced and starred in 'Punk'd', playing gags on Hollywood stars such as Justin Timberlake and Frankie Muniz.
The cruel assaults weren't always well appreciated by the stars and now Kutcher fears doing such juvenile crap could cost him future acting roles.
He says of the potential blacklisting because of his antics: "You punk your co-stars (and) people won't want to work with you anymore. So I kind of had to lay off of that."
His 'What Happens in Vegas' co-star Cameron Diaz was glad to hear the actor she wouldn't be a hapless victim of his practical jokes and that Mr Demi Moore has finally grown up.
"He's figured that out because the biggest thing when you're doing a partnership like this is trust and if you don't trust the person, if you think around every corner you're going to get slapped in the face, it's not so fresh."
