Has all the plastic surgery messed with Heidi Montag’s head?

Hills villain Kristin Cavallari thinks so!

“She changed her number, so I can’t get a hold of her,” Cavallari tells E!’s The Daily 10.

At a recent MTV photo shoot, Montag showed up with four bodyguards and refused to pose for pictures with the rest of her Hills cast-mates. The plastic bitch appeared to be on some straight-up diva shit!

Montag recently began her own campaign to become the next blonde Tomb Raider, all of this comes after her brief cameo in a new Adam Sandler movie, Usmagazine.com reports.

“No one saw her because no one was allowed to speak to her,” Cavallari, 23, tells E!. “She didn’t take the group photo with us which was really disappointing.”

Surprisingly, K-Cav did have one compliment to dish to Heidi.

“Honestly, Heidi looks better in person.”

The cast has been gearing up for the final season of The Hills, which begins April 27.

Can we expect one last appearance from The Hills first lady, Lauren Conrad?!

“I hope Lauren comes back,” Kristin says. “I think it would be awesome if she comes back.”

All of their 15 minutes are up. Sorry Girls.

Kristin Cavallari is finally getting the attention she’s always wanted…

The new star of The Hills raised eyebrows over Super Bowl weekend in Miami: “She was wasted the entire time,” a source tells Us Weekly. “She was going around to everyone, asking them to score her some coke.” However, Krisitn’s lawyer refutes the allegations to Us and MTV is refusing to comment.

However, everyone close to Kristin and her party-girl ways say that that behavior has become more and more typical. “Her issues are becoming apparent to everyone,” an insider reveals. “She’s getting scary-thin and not showering regularly…She’s clearly unhealthy.”

Additionally, all her pals from The Hills are urging her to check into rehab, but to no avail. “She doesn’t think she has a problem,” a source says.

And unfortunately, her poor choices are hurting her career, as well as her health. Her erratic behavior has caused her to become chronically tardy to Hills tapings, when she decides to actually show up!

And to only make matters worse, her risky lifestyle might become a focus on MTV’s hit show. “Her drug problem finally became an unavoidable conversation topic on film,” an insider says. “If MTV uses the footage, it will be clear to everyone.”

Hmmm… Kristin sounds like the next generation LiLo! It’s only a matter of time till she’s workin lesbian tendencies and twittering her problems! Go to rehab now Kristin and save us the drama…

It seems like all Hills star, Kristin Cavallari cares about is drama and boys, but it looks like she’s a bit deeper.

Last month, she left the Hollywood Hills to do some charity work in El Salvador.

“Going to El Salvador was such an incredible experience,” Kristin, who traveled to the Central American country on Jan. 14, tells Usmagazine.com. The MTV star helped spruce up a local school with murals and played with the students.

“It really put everything into perspective and made me appreciate everything I have,” Kristin continued. “Seeing how happy and excited the kids were was the best feeling in the world.”

Later this year, after filming the sixth season of The Hills, Kristin will travel with the One Kid, One World organization in a goodwill trip to Kenya.

You go girl!

Does The Hills’ favorite bitch, Kristin Cavallari, want a piece of Jersey Shore’s, The Situation’s situation?

“I’m not going to lie, I’m kind of jealous,” Cavallari told Usmagazine.com when asked about the new hit MTV show at her 23rd birthday party Saturday at Beso, Eva Longoria Parker’s Las Vegas restaurant that connects with her nightclub, Eve.

Beating The Hills out of the water with ratings, The Jersey Shore continues to hold the spot for MTV’s most watched show, and Kristin explains why…

“The Situation,” she told Us. “I mean, come on, right?”

Would Miss Hollywood ever date an super-tanned fist pumping guido?!

“Maybe, if I liked him,” she told Us. “I mean, if I was attracted to him, absolutely.”

Hmm, shall The Boots Girls play matchmaker this weekend when The Situation and DJ Pauly D hit up Lumen nightclub?!

We all know the story about how the new Hills ho, Kristin Cavallari stole Audrina Patridge’s ex. Well, it looks like she’s done it again!

Recent reports claim that Krisitn is now dating Tal Cooperman (co-owner of the DCMA Collective clothing line), who Audrina once had a friendly fling with. According to Usmagazine.com, though, Audrina doesn’t even care!

“Audrina thinks it’s laughable. Tal and Kristin have gone out a few times now, but it’s nothing serious. Tal and Audina never officially dated and are still friends.” a source tells Us.

But in her own opinion, the source also commented, “Why does she continue to chase Audrina’s sloppy seconds?”

We were just thinking the same thing…

However, despite the drama that goes down on the show, Audrina recently mentioned that she and Kristin are on better terms these days.

“At the end of the day, it’s a show,” she says. “It’s entertainment. And you can’t take anything serious on that show.”

Well obviously! In what world what two hot chicks fight over a nasty loser like Justin Bobby?! Come on ladies… homeboy wore combat boots to the beach.

You’d think seeing your ex hook up with someone on national television would put a real damper on your day. However, Hills star Audrina Patridge says it’s not difficult at all seeing her ex Justin Bobby lock lips with her onscreen enemy, Kristin Cavallari.

“At the end of the day, it’s a show,” Audrina tells Usmagazine.com. “It’s entertainment. And you can’t take anything serious on that show.”

However, their feuding days were initiated on the season six opener when Kristin pursued Audrina’s homeboy.

When asked if Kristin and she had resolved any of their issues, Audrina responded, saying “I don’t know. I really don’t know how it’s going to play out. We still have three weeks of filming - and that’s it.”

This will be Audrina’s last season of The Hills. She’s moving on to star in her own reality show, to be executive produced by Survivor creator Mark Burnett.

“I’m an adult now, and I don’t need all the petty drama and drinking and fighting,” Audrina, who tragically just split from HOTT Aussie BMX racer Corey Bohan recently told Maxim. “I’ve done that, and I’m ready to move on.”

Amen sister! We’re over the petty drama too! Honestly… we think bringing that annoying little biotch Kristin to the show was the worst move MTV could have made. Talk about trash TV…

The bitch certainly is back! Kristin Cavallari wasn’t shy to run her mouth on last night’s premiere episode of The Hills and as usual, she’s sounding off about her fellow cast member’s behavior!

Viewers last night watched as Kristin and Audrina Patridge engaged in a full blown bitch fight after Kristin got her flirt on with Audrina’s ex-fling Justin Bobby.

“I think that Audrina and Stephanie [Pratt] were very judgmental and just wrote me off right away without getting to know me,” Cavallari told Usmagazine.com Tuesday at the “Unite Unveiled: Gen Art’s Fresh Faces in Fashion” event in West Hollywood.

So was Kristin’s attraction to Justin Bobby legit or just one of her usual bitchy moves?

“You’ll have to see it on the show” — but she told Us “the love triangle” gets “pretty dramatic” as the season progresses.

You mean the love triangle created by MTV just to cause drama and boost ratings? Like we really believe any of this shit is real.

What does Kristin think of Audrina’s sudden appearance transformation since the first season of The Hills?

Before taking another stab at Audrina she laughed.

“I’m not commenting on her plastic surgery,” she told Us.

It’s amazing how shitty this show really is, yet we all keep tuning in…

So, who’s raking in the most moolah on MTV’s The Hills?

Although it’s only her first season, Kristin Cavallari earns $90,000 an episode!

Seems excessive right? Well, according to figures reported by the Daily Beast, Aurdrina Patridge and “Lo” Bosworth both earn $100,00 per episode!

As for Speidi, Heidi Montag nets $100,000 as well, but Spencer Pratt only gets $65,000.

And after discovering that Lauren Conrad made a whopping $125,000 an episode, we wonder why she ever left the show! She even had in her contract that no other character could match her salary.

Finally, poor Brody Jenner earns the least at $45,000 a show.

Essentially, these idiots earn thousands upon thousands of dollars for walking around, being their stupid selves while a camera follows them. Seriously?! It’s not like we’re in a recession or anything…

That’s shocking! We thought John Mayer did anything with a va-jay-jay!

Mayer, who’s practically known for doing anything that walks, is really adamant about letting the world know that he did NOT bang The Hills’ new bad girl Kristin Cavallari.

Oh, and of course he went to his page Wednesday to address this crazy rumor!

“Rumor control: How do I put this like a gentleman…I have never high fived Kristin Cavalari with my penis,” read his first post.

Hold on…his RIDIC tweets didn’t stop there!

He then went on to say, “I’m sure she’s a wonderful gal but we have never tasted the Skittles Rainbow together.”

“My Milli has never slam danced with her Vanilli,” he continued.

Finally, he ended by writing, “I have never Bensoned her Hedges, nor have I attempted to Bartle her James.”

John Mayer is such a disgusting tool! We’re actually really surprised these two whores haven’t found there way in an out of each other…

Lauren Conrad never really liked Kristin Cavallari so she’s really not surprised her Hills co-stars don’t like her either!

“I think she is just very opinionated and that’s how she has always been,” Conrad told Usmagazine.com at the MTV Movie Awards on Sunday, adding that she’s already “gotten a few emails” about her replacement.

So what advice did she give her friends when dealing with the drama queen?

“You know, it’s the same as dealing with anybody. I said, ‘Be yourself.’ That’s all you can do.”

Audrina Patridge has made comments in the past about how she and Kristin don’t totally get along. And now Stephanie Pratt is expressing her dislike for her too!

“We are not really fans of her,” Pratt told Us on Sunday. “She doesn’t want to be friends with us. She wants to bring her acting skills to The Hills and yell at all of us.”

She continued by saying, “I have no idea why she doesn’t like us. I actually just had lunch with Lo [Bosworth] the other day, and we were just talking about how crazy this is. She was telling me some interesting things about her in high school.”.

Despite the drama, Frankie Delgado told Us that Kristin will bring “her little perkiness” to the show.

“I think it’s going to bring a whole new different life to the show,” he said. “I think with Lauren it was her story. Now it’s time to bring in somebody else’s story.”

Kristin, he added, “is just full of energy. You never know what to expect from her. We have shot twice with her and both times it was drama!”

Even Brody Jenner, Kristin’s ex, is excited to have her join the show!

“Kristin and me get along just fine. They don’t like Kristin because she brings so much drama. I think it’s great.”

Kristin? Drama? You’re kidding…
