"If it was the right thing, yeah. I would love to costar with Justin," Jessica Biel tells Parade.com. "I just don't know what the right thing is, though." When it comes to their relationship, Biel admits she's "really careful" not to reveal too much.

"Once you start to go there you really are opening your life which is already so open," she says -- and then begins opening about their two-year union. "Anyway, we don't do much of anything. We certainly don't do anything interesting.

"We just hang out at home. You have to have a real life because of the kind of crazy Hollywood stuff that you can get wrapped up in," she says. "It's so important to have hobbies and girlfriends, and not know people that work in Hollywood. It's a sanity thing; it keeps you sane. I was playing soccer and I joined a kickball league. That's way more interesting to me than going to some party."

"I was looking at this script for a Robert DeNiro film and there was so much nudity in it. I just was like, 'I can't do it,'" she says. "It took me a long time to really finally say no to that one."
