Lauren Conrad knows a thing or two about rumors, and the latest one making rounds is that her boyfriend-stealing nemesis from

Laguna Beach,

Kristin Cavallari, is joining The Hills. "No!" Conrad said between laughs when TV Guide caught up with her at the Kari Feinstein's Style Lounge. "That's a rumor." Even rumors that Conrad's best friend Audrina has switched over to "Camp Heidi" (as in Montag) are highly exaggerated. "Audrina has always been cordial with Heidi," LC explains. "We still live together, we're still best friends. Audrina is always going to be able to say hi to people she's known, and people are just taking it a little further." And although Conrad didn't mention whether or not she and co-star Whitney Port still have jobs, she did confirm that Whitney isn't going anywhere: "She's not going to leave the show. I've asked her to move in [with me and Audrina] so you never know, but she's not as comfortable with the cameras. We literally wake up to them setting up in our house and she's like, 'I couldn't deal with that.'" - Carita Rizzo
