Lauren Conrad and Kristin Cavallari will likely never be the best of friends, but now that they've grown up and matured, it's clear that their days of high school feuding and drama from Laguna Beach are long gone.

Lauren made this fact apparent during an interview with Andy Cohen on Watch What Happens Live, when she was asked to say three nice things about her former nemesis. "She's really good at losing baby weight. That's true!" she says. "She is a very pretty girl. There's a lot of nice things! I was just trying to get more specific. She dresses really nicely!"

Although her days on The Hills are long gone, that wasn't the only question Lauren was asked of her former co-stars. When asked to choose who she'd "marry, shag and kill" between Spencer Pratt, Brody Jenner and Justin "Bobby", she jokes, "Can I kill myself?! I'll plead the fifth!"

Andy also brought up Lauren's ex-BFF Heidi Montag's major plastic surgery from a few years back. "I thought she was beautiful before it," Lauren admits. "I don't think she needed it. But, personal decision."

Oh, LC -- always a class act!

Do you think Lauren and Kristin can ever be BFFs?!
