Anyone who's been watching MTV's sorta-reality show The Hills this season knows that Audrina—the kind of hanger-on in star Lauren Conrad's orbit who managed to worm her way into Lauren's life and become her roommate and new BFF once former BFF Heidi spread those nasty rumors about her and started dating the spawn of Satan—has this kind of vapidness that either indicates she's really, really stupid, or she's just decided to play the stupid one on the show. Because really, it boggles the mind to think that she actually believes that her loser ex-boyfriend just magically decided to reappear in her life during the third season of her wildly successful reality TV show! But that seems to be what she's throwing down.

"Of course we have our feuds and everything, but it's fun having him part of the show," says the Epic Records staffer, 22. "He is so cute!"

In their corner?

Pals of the reality star, who have watched the couple's two years of off-and-on dating, say they've seen plenty of evidence that the hairstylist, 25, is The One.

"The core people around Audrina's life know what Justin means to her," says a friend. "It's not like he's just pursuing her to be on the show - he is dealing with the show so he can continue to be part of her life."

It's a gesture not lost on Patridge.

"He is so not used to having the cameras around," she says. "He hates it, but he does it for me."

Aww. So selfless, that one! And: As if!
