The Hills Final Season Trailer

In a sneak peek of the final season of The Hills, Heidi Montag comes home after undergoing 10 plastic surgery procedures in one day.

"I haven't seen anyone since my surgery -- no one's seen Heidi 3.0," she says.

But when she asks her mom whether she looks good, her mom refuses to answer.

"I think you should rephrase the question," says her mom.

That isn't Montag's only drama next season: The trailer hints that she is and husband Spencer Pratt are on the rocks ("I really didn't think that on my year anniversary I'd be getting divorced," she says).

Elsewhere, Lo Bosworth also confronts Kristin Cavallari about her alleged cocaine use ("We're worried about you," she tells her) -- and much more!
