Brody Jenner: Where in the World Is Lauren Conrad?

The two Hills celebs used to be tight, but not anymore. What's going on now?

Audrina Patridge apparently isn't the only Hills starlet Brody Jenner isn't hanging out with at the moment.

Believe it or not, the once inseparable Brody/Lauren Conrad duo is no longer attached at the hip.

"I haven't seen much of her since she left the show," Brody admitted to us recently. "I ran into her out and about a week ago just by chance, but that's it."

So what's the deal?

"She's off somewhere—uh, Indonesia?" Brody joked. "I don't know, maybe on her honeymoon?"

It's not like L.C.'s replacement, Kristin Cavallari, isn't keeping everyone on their toes. "Kristin's obviously a little more opinionated, and she comes in there and likes to stir up the pot," Brody says. "Lauren's more docile and she likes to just let things cruise by. It's a different energy."

With all the fighting that goes on among the Hills regulars, will there ever be peace and quiet for the bickering bunch?

Maybe some.

"There has definitely been some reconciliation," he said. "I can't tell you who it was with, but there is some drama that has been put to an end."

We have a feeling he is not talking about his Playboy model girlfriend, Jayde Nicole, and Audrina.
