Get ready for drama!

Judging by the first official trailer for the new episodes of The Hills, there’s going to be plenty to talk about when the show returns to MTV on Sept. 29.

“She’s the girl that’s going to stab us all in the back and she doesn’t care,” Stephanie Pratt says about Kristin Cavallari‘s anticipated return. “How can one person turn all our lives upside down?”

Here’s how: Lauren Conrad‘s Laguna Beach rival also dated Brody Jenner, so his Playboy Playmate girlfriend Jayde may need to watch out.

Although Audrina thinks she’s moved on from Justin Bobby, she may not be ready to see him with another girl. And guess what — Kristin also has her eye on Audrina’s ex, who she met at Spencer and Heidi‘s wedding.

Speaking of … It looks like Heidi has been bitten by the baby bug! In the trailer, she’s hinting that she may be ready to start a family. Are you ready for a little Speidi offspring? Neither is Spencer, so rest easy — for now!

Heidi and Spencer are also concerned about her sister Holly, who she says may need to head to rehab.

As the trailer wraps with dramatic clips of Kristin stirring up trouble with some fighting words — and a kiss! — the producers of The Hills have a final note about their new star: “The bitch is back.” –Aaron Parsley
