Sarah Jessica Parker's on-screen ex, John Corbett, co-starred with Kristen Stewart in the 2007 horror flick The Messengers – and he still stays in touch with the actress and her family.
So did he have any inkling that Stewart, 20, would become household name? "I thought Kristen was a rockin' actress back then, but you never know anyone's going to be a phenomenon when you're working with them – especially at that age," he tells PEOPLE.
The actor says Stewart’s overnight rise to fame has not been an easy adjustment for her family.
"I saw Kristen's dad John, and we were talking about this phenomenon she has become, and quite frankly what a pain in the ass it is for her, too," says Corbett, 49. "I think 'bizarre' is the word to describe how Kristen's dad feels. It's his little girl, and I think he feels very protective over her. I'm not putting words in John's mouth, but it's not natural to have your kid be the subject of so much attention – wanted and unwanted.
Corbett says he regrets not chatting with her dad about – who else? – Robert Pattinson.
"That's the one thing I should have asked him about, but we didn't get that far," Corbett says. "If he and Kristen really are dating, I think they'd be a good match. They seem like two really sweet youngsters. Kristen was beautiful back when I worked with her, and I knew she would blossom into a beautiful woman."
