But, of course, Jamie is only kidding!

"No, I love working with them," he said. "They're both incredible actors and Kristen's someone I've admired for ages since I first saw her in Panic Room I've thought she was wonderful. And Rob is someone who mutual friends of mine now know as well, so it's nice to be able to work with people that you can get along with."

And he did actually spend time socializing with the Twilight twosome too!

"When we were filming we did a lot, but they're working a lot and they have to go everywhere, they don't really have a home, you know," he explained. "Well I suppose a hotel would be a home."
