Is LC's Former Sidekick Playing For Team K-Cav?

As Lauren Conrad's on AND off-screen best friend, we figured Lo Bosworth would join Audrina Patridge (and apparently Stephanie Pratt!) in the newly formed Hillzies Against Kristin Cavallari coalition. But now, it's starting to look as though Lo might be standing by K-Cav -- whom she recently described as a longtime Laguna pal.

"I find myself kind of acting as a mediator between two different groups of people," Lo told E! Online about her role on this season's Hills. "I've known Kristin for years and she's my friend. And then I have [Stephanie Pratt and Audrina] who are like, 'Who is this girl? Why is she here?'"

And while we're surprised to hear Lo's warming up to one of Lauren's high school rivals, this wouldn't be the first time Lo and Audrina found themselves at odds. Sure, they've been getting along great as of late, but we still remember the time 'Drina shouted "We'll never be friends!" shortly before moving out of LC's guesthouse. And something tell us Lo remembers it, too...
