Are Brody Jenner and Kristin Cavallari back together? Not so fast says reps for the two, but diners spying on the pair at a recent Hollywood dinner (i.e. taping for The Hills) say the two were shooting sexy stares and come hither vibes all over the place. Ewww.

Brody and Kristen dated back in 2006, but could a little Hills season fling be in store? Popeater reports:

A diner at the restaurant says Cavallari and the engaged Jenner “definitely only had eyes for themselves,” and that “they had their back to everyone else in the crowded restaurant. It was like no one else was there…There was definite electricity. I’d say 8 out of 10 and a lot of eye contact. Whenever the wait person came over to their table it was like something was being interrupted,” an observer said.

They were probably just trying to remember their lines. Duh! I love how none of the “diners” mention the camera crew.

And here comes the predictable response from Kristen’s rep:

“The two are very good friends and that’s about it.”
