Ashton Kutcher Promises Not to Punk Brittany Murphy  4/20/05

Ashton Kutcher has promised ex-girlfriend Brittany Murphy she's safe from ever getting pranked on his hit show Punk'd - because he finds her far too gullible.

While Kutcher has fooled countless celebrities - including Justin Timberlake, Halle Berry and Salma Hayek - on his TV hit, he's decided to declare his Just Married co-star Murphy exempt.

The actress tells MAXIM magazine, "He would never punk me. I was always afraid he was going to when we were together, but one day he told me, 'I'd never punk you; you're far too gullible. There'd be no fun in it.'

"And I am, I'm extremely gullible."
