Lauren Conrad, Heidi Montag Supposedly Make Up

The unthinkable has happened. No, not Sarah Palin in Playboy.

The Hills' bitter enemies, Lauren Conrad and Heidi Montag, are friends again after making up at STK in Los Angeles Tuesday evening, according to reports.

LC was in the restaurant celebrating her runway show (her fashion line was featured at Los Angeles fashion week) with family and some close friends.

Wouldn't you know it, in this small Hills universe: Heidi Montag and Spencer Pratt just happened to be at the bar eating dinner. The plot thickens.

After spotting her nemesis Conrad, Montag was seen asking Spencer if she could congratulate her former roommate and BFF on her clothing line.

Apparently the jerk allowed it. And after a brief heart to heart, the two girls were seen hugging. They were both smiling and seemed happy to talk.

"It's true. Heidi was at STK. She came in to the after party to congratulate me on the show," Conrad said. "It was nice of her. I appreciated it."

Are you happy they made up? Should LC and Heidi be friends?
