"The Hills" Audrina Patridge finally dumps her caveman boyfriend.

She'll be back with him soon enough. .....Did I just post about "The Hills" again??....Sigh...........
US:
"I caught him doing something he shouldn't have been doing and it was just the last straw," Patridge, 22, tells Us of her October 16 fight with Brescia outside of L.A. nightclub Opera.
What was Justin Bobby up to?
A Hills source says he was "making out with a red-headed girl right in front of Audrina, and when she confronted him about it he laughed in her face."
Patridge tells Us, "It was one of the hardest nights ever I've had to deal with. And it was on camera too."
