It's no secret Kristin Cavallari planned to shake things up in Hills country. But we had no clue that meant sucking face with Justin Bobby, ripping on Brody Jenner and challenging Stephanie Pratt to a Celebrity Deathmatch. Meanwhile, Heidi Pratt's got baby fever, Holly Montag's got a (possible) drinking problem and Audrina Patridge has got MAJOR friction with the new girl. Get a sneak peek of K-Cav's reign of terror official series debut, and catch new episodes of The Hills starting Tuesday, September 29th at 10pm. You're not in LC country anymore ...

Lauren Conrad had only nice things to say about leaving her Hills legacy in the hands of Laguna drama queen Kristin Cavallari. But that doesn't mean she'll have her eyes glued to the small screen for K-Cav's second-coming.

So will she even be tuning in? As of now, the answer's a big, fat NO.

"I probably won't watch it," LC confessed to E! Online. "I'm not a huge TV person." (Betcha never thought you'd hear a reality TV star say that!) Meanwhile, though LC sez she's not so much into watching the boob tube, she's apparently not above writing -- or starring in -- any new shows. The Hills alum just confirmed rumors that she's looking to get her book L.A. Candy adapted into a new (unscripted?) series and admits she hasn't ruled out a return to TV Land herself.

"I actually asked not to hear [any pitches]," Lauren said of her post-show protocol. "I said, 'Don't tell me anything.' So problem solved, and I got to enjoy some time away. But," she concluded suggestively, "my two months is up now."

+ Assuming she's for realz, would you watch Lauren on a new show? Take the poll and tell us whether you're Team LC for life!

K-Cav may be the new It Girl in town, but we’re wondering if she can hold a candle to her predecessor when it comes to fashion. Her first test: last weekend's "A Time For Heroes" carnival, where she and Lauren Conrad shared the same exact airspace -- and posed for the exact same photogs -- without even THINKING the word "catfight." (And they said this Kristin chick was supposed to be dramatic!)

So who had the snazzier dressed-down style? Scope out these pix of former Laguna ladies LC, Kristin Cavallari and Lo Bosworth (plus award-winning Hillzie Stephanie Pratt), then tell us who you think looked cutest in casual wear. May the best girl win!

No, Audrina hasn't fallen prey to the charms of gaseous biker-slash-ladykiller Justin Bobby again (or beamed her way back into Chris Pine's atmosphere). But during a fun-filled weekend in Sin City ('Drina hit up Vegas for her sexy Carl's Jr. commercial shoot and her brother's bday bash!), the Hills gal DID cozy up to one of her other exes: Aussie BMXer Corey Bohan. Oh, and by "cozy up to" we mean "made out with repeatedly" and "grossly sat in his lap." (See: People.com for clarification/proper usage.)

So will the Vegas reunion turn into something more? We're not sure, yet -- but from what we saw on The Hills, Corey and Audrina actually make a cute couple! Or at least they would have, if Audrina'd ever gotten Justin off her mind long enough to appreciate him.

Hmm, maybe now that Audrina's done with JB for realzies (fingers crossed!), she can finally give Corey the shot he deserves! Then again, if she's 100% over Justin, why's she all up in Kristin Cavallari's face about maybe-dating him next season?

So far Kristin Cavallari's popped up on exactly one episode of The Hills -- but she's already managed to intimidate Lo, scare the bejebus outta Stephanie and get her name plastered across the top of Audrina's shiz list. And those aren't the only peeps she's rubbed the wrong way. Tattles the New York Post's Page Six:

"[Kristin Cavallari] was hosting a fashion show at club Tantra in St. Maarten with Victoria's Secret beauty Selita Ebanks when she decided to playfully toss some glitter at catwalking models, who didn't appreciate the gesture. 'After the show, four of the models had to be restrained from trying to start a fight with her [...]' says a spy. 'One of them grabbed her by the hair before the fracas got broken up.' Club security eventually escorted the miffed models out before anyone broke a nail."

Hear that, folks? A few minutes of Kristin was all it took to turn a roomful of international supermodels into a bunch of catfightin' Girls Gone Wild! Now, multiply that anger times ten, throw in a pinch of possessiveness and you've pretty much summed up 'Drina's feelings on the whole Kristin-and-Justin Bobby sitch  ...

Although Lauren Conrad doesn't regret walking away from The Hills, she wants fans to know it wasn't an easy decision.

"It was a bittersweet night for me," Lauren blogged the day after the Hills season finale aired. "A part of me is sad to say goodbye to something that has been such a prominent part of my life, but I know that it was time and I am very happy with my decision. I want to take this opportunity to thank everyone who has watched and supported me over the years."

"While putting my personal relationships and struggles on television wasn't always easy," she continued, "the support I received from people made such a difference. Because of all of you, I was able to accomplish so many aspirations and for that I am very grateful. So, THANK YOU EVERYONE!!! I have some interesting projects in the works and I will keep you all updated."

So how does LC feel about leaving the show in Kristin Cavallari's hands? "From what I've heard," she wrote, "the next season will not disappoint." Based on what we've seen so far, we'll have to second that notion.

Although The Hills' new leading lady, Kristin Cavallari, has been all sortsa noisy about her strategy to stir up trouble next fall, we had no idea that all holy hell would break loose in the first couple of episodes. Watch the trailer below, in which K-Cav swiftly befriends the controversial Stacie the Bartender, more-than-befriends Justin Bobby and then ignites World War III with Audrina, all while looking incredibly pleased with herself.

She wasn't kidding yo ... The bitch is back.

Stephanie Pratt recently admitted that she's worried about getting on Kristin Cavallari's bad side. But apparently, Audrina Patridge has no such reservations. The feisty brunette dished about her new costar yesterday on Ryan Seacrest's radio show. "I don't like her," she confessed. And it was only downhill from there.

Later in the interview (excerpted on Usmagazine.com), 'Drina said that she and Kristin got into a fight on the very first day of filming! And while she refused to say whether or not Justin Bobby was the cause of the drama (Kristin's been equally coy about rumors that she and JB have been dating), Audrina was clear about one thing: she has no problem standing up to Kristin.

"When someone gets in my face, I have to defend myself," she told Seacrest. "[And] it's really pathetic and desperate what people will do when the cameras are around."

"Pathetic"? "Desperate"? Wow, better watch what you say, Audrina! Those sound like fighting words to us. And we all know Kristin Cavallari's never been one to shy away from an argument ...

Usually the gal who gets the most attention walking down the aisle at a wedding is the bride. Not so much on the upcoming season five finale of The Hills. Like Zoolander to the runway, Kristin Cavallari struts onto Lauren Conrad's scene and promptly a) makes sexy eyes with Justin Bobby and b) seriously pisses off Audrina. Season six is gonna be a good one...

Get a sneak peek of Sunday night's Hills finale now!

Stephanie Pratt may have her reservations about Kristin Cavallari, but she's "excited" about the prospect of partying it up with Lauren Conrad's replacement. Spencer's sis recently sat down with PopEater.com to explain why she's equal parts thrilled/terrified at the prospect of hangin' with K. Cav. Here's what she had to say:

"I just met [Kristin]. She was really, really nice and she was the kind of person that if I see out, I'd say hi to her because I feel like I know her because she's known Lauren and Heidi forever ... but I just read [how] she's not coming to make friendships, so I think we're all a little scared. We're excited because Lauren wasn't going out that much at the end, so Kristin's all ready to party."

And while Steph's got a reputation on The Hills for being a bit of a pot-stirrer (bringing Heidi to Lauren's surprise party? Seriously??), she says she's not looking to start any trouble with the newest Hillzie.

"I've had such good luck with making friendships with these girls, so I'm optimistic I can make a good relationship with Kristin."
