The Hills Stars Kiss And Make Up

(Photo: Splash News Online) Heidi Montag and Lauren Conrad, stars of MTV's The Hills, have been feuding for years. However, now that Montag has (or hasn't) tied the knot with costar Spencer Pratt, the ladies are burying the hatchet.

"I know how to be her best friend, and I know how to hate her, and I don't know how to do anything in-between," Lauren says to her roommate Lo Bosworth on the show.

Then, when the two meet, Heidi embraces her and says, "The only thing really missing in my life is you. It's really hard."

All this and the real wedding (or not) on the season finale of The Hills.
