Sunday's finale of "The Hills" Season 5 marked the arrival of a new face: Kristin Cavallari, who will fill the role occupied by former lead character Lauren Conrad.
Lauren and Kristin were high school rivals on the MTV reality series "Laguna Beach." Sunday was Conrad's final appearance on "The Hills."
On the show, the two 20-somethings crossed paths at the wedding of "Hills" stars Spencer Pratt and Heidi Montag. They showed up in similarly colored dresses.
As Lauren rode off in a limo, Kristin told co-stars Lo Bosworth and Audrina Patridge she was looking for a guy to date. She later caught the Heidi's wedding bouquet.
A trailer for the sixth season of "The Hills" showed a potential relationship between Kristin and Justin Bobby, Audrina's ex-boyfriend. The new season will premiere in the fall, it said.
Will you watch "The Hills" without Lauren? Can Kristin fill her shoes? And how long will Spencer and Heidi's marriage last?
