Lauren Conrad Lauren Conrad and Heidi Montag have done the unthinkable.

These arch enemies have kissed and made-up.

Let's see how they buried the hatchet...

The Hills pair apparently bumped into each other in STK restaurant in LA.

Lauren was there celebrating her latest catwalk show of her fashion line, while Heidi was there with her fella, Spencer Pratt, having a romantic dinner.

The word is Heidi took the first step to friendship by going over and congratulating Heidi on her fashion show.

And the buzz around Hollywood is that after some deep and meaningfuls the two gals were seen hugging it out.Heidi Montag

Lauren told Us mag: "Yes, it's true. Heidi was at STK. She came in to the after-party to congratulate me on the show.

"It was nice of her. I appreciated it."

It seems to us that Heidi has been itching to make pals again with Heidi - she recently told Extra: "Obviously I miss her, and she was my best friend for a really long time.

"Hopefully one day we will be able to work through this and move on and patch some things up."

Hhhmm... it's a start but we'll wait and see.
