Did you watch The Hills last night? Nothing the show cooked up has anything on the latest Lauren Conrad scandal. Rumors have surfaced that LC hooked up with Justin Bobby, Audrina Patridge's on/off BF. According to Perez Hilton, Audrina learned of the alleged hookup a week or so ago from a friend of Justin Bobby's. (Could that be why she moved out?!) And when Audrina confronted Justin Bobby, he totally admitted it!

But LC is saying hells to the N-O, denying that she'd ever be interested in Audrina's man: "Do they think I was swept away by his wonderful manners and his commitment to my friend? I love it when guys burp in my face. So hot!" she blogged on her MySpace last week. "I have never even been in the same place as Justin when Audrina wasn't around. I have been there for Audrina for years of ups and downs with this guy. Now she is accusing me of hooking up with him?"

And while Lauren has made a plea to her pal ("You know I didn't do this and I have never given you a reason not to trust me," she wrote. "Whoever is telling you these things does not have your best interest at heart. You asked me if I did this and I told you I didn't."), it doesn't seem like Audrina's interested in listening. She was spotted having lunch with Heidi Montag over the weekend!

Now, we can't picture Lauren and Justin Bobby ever getting together, but the damage has been done. The battle lines have been drawn, kids...
