In real life Rumer Willis has a great relationship with her parents Demi Moore and Bruce Willis – but she'd like the chance see what their family dynamics are like onscreen.

"You know I'd really love that," Willis, 21, said Thursday night at the Los Angeles premiere for her new movie, Sorority Row. "I think it would be really fun to able to play an opposing character, so we'll see how that works out."

After all Wills says she's watched her parents' careers as a model of success. "I want to take my acting as far as I can," she says. "I think one of the best things in my life is that I got to see at a young age what I wanted to be."

In the meantime, the actress, who will appear on 90210, says she's getting plenty of support from her folks.

"They're just so unbelievably supportive of me and that's all I could ever ask for," she says.

As for her boyfriend, actor Micah Alberti, he seems to have overcome Bruce Willis' famously protective stance toward his daughters. Rumer says things between her and her beau are going "fantastic."
