Everyone on "The Hills" seems to agree that [article id="1621511"]Kristin Cavallari is stirring up a lot of trouble[/article] for the new season of the show, which kicks off on Tuesday (September 29) at 10 p.m. ET. Brody Jenner, Cavallari's former flame, admits that there are no hard feelings between him and the "Laguna Beach" veteran.

In fact, he's actually kind of excited to have her hanging with him on the show. " 'The Hills' this season is completely different," he told MTV News. "It has a new feel, and I think it's fresh. Kristin adds such a different element. ... I think for a while 'The Hills' was just kind of focusing on ... I don't know, I'm going to give my personal opinion, but I think it was getting kind of soft there for a minute."

If it was getting soft, then Kristin will definitely make sure she makes life hard for everyone on the show. "It was just the same thing over and over and Justin and Audrina and yada, yada, yada, so I love to see Kristin's attitude coming into it," Jenner said. "She adds a whole new thing, and she's causing all types of drama that probably never would have happened if she wasn't involved."

Jenner, however, knows that [article id="1622476"]Lauren Conrad will be missed[/article] by the fans, and he even admitted to missing her himself. But he also thinks that if fans give Kristin a chance, they'll enjoy what she brings to the table. "Keep an open mind and watch," he advised.

"Get your popcorn out, get whatever you do, but it's a crazy show this year."

To see if Kristin Cavallari can fill Lauren Conrad's shoes, tune in to MTV on Tuesday at 10 p.m. ET for new episodes of "The Hills."
