MTV recently enlisted the services of Laguna Beach alumna Kristin Cavallari to drink, party, hook up, drop f-bombs and wreak general havoc on The Hills.

The cost? Just $63,000 per episode.

According to Life & Style Weekly, the new replacement (and former high school adversary) of Lauren Conrad will earn that sum beginning next fall.

LC was reportedly netting $65,000 per episode from the "reality" show.

An insider says of Cavallari, who had not been heard from in three years, but magically appeared as the central character in the lives of The Hills stars when MTV desperately decided to resurrect her after Lauren Conrad said she was leaving:

“They needed someone new and fresh, who also came with a buzz and a name that was recognizable. Kristin was the obvious choice. She wanted money. You don’t have to pay the other girls that kind of money, but for Kristin you had to pay up.”

Apparently. But the rest of the cast is all for it.

“She’s so fun and crazy. Kristin’s not afraid to put anything on camera. She’s not going to hold anything back," said plastic co-star Heidi Montag.
