The Hills star Audrina Patridge and her cute sister exit Club Villa.

Audrina is our favorite one from that MTV reality show.  Could you believe how nasty that “Lo” girl was to her in the last show?!  It was obvious how jealous of Audrina she is!

Team Audrina!

Times have certainly changed with The Hills gang!

Cutie Audrina Patridgecelebrated her birthday in Las Vegas Saturday night without the annoying Lauren Conrad.

The now 23-year-old (her actual birthday was May 9) drank Grey Goose and Red Bull and goofed off with pals — including her mom! — at club LAX.

Wearing a black spaghetti strap dress, Patridge danced to Akon’s “Smack That” while a female pal slapped her booty.

At 12:40 a.m., a white-frosted cake decorated with roses was brought out. Patridge — who flew in from Hawaii, where she’s filming her first movie Into the Blue — grabbed a rose and licked frosting off the stem.

An hour later, Patridge flirted with a guy friend by giving him a peck on the lips, and later stole his fedora hat off his head.

So why didn’t Conrad, 22, party with her pal in Vegas?

“Obviously there is tension and other things going on,” Conrad said at the Hills season finale party in Beverly Hills last week.

“I mean there are things in our relationship, but that’s how every relationship is,” Conrad added. “You fight, you make up, you get along…obviously we are going to have problems, but we are still friends and we love each other.”

Riiight!

Team Audrina!

Lauren was probably at home obsessing over some guy who really isn’t into her, while “Lo” Bosworth wipes her tears.  Audrina would be a thousand times more fun to hang out with!

Check out Heidi Montag’s appearance on David Letterman last night. I can’t quite explain what is happening, but I’m a little more Team Heidi lately. I think Lauren Conrad and Lo Bosworth have been pretty rude to Audrina Patridge lately and that is ticking me off. I actually believe Heidi’s story about the Lauren Conrad and Jason Wahler sex tape. Remember when Lauren stopped talking to her friend that hooked up with Brody, but she still wanted to be friends with Brody? Well, it would make sense that Lauren would be pissed at Heidi, and not at Jason, her ex, the one who was actually trying to sell the sex tape. Check out the video and see what you think.

Heidi Montag and Lauren Conrad agreed to put away their cat claws – for one day at least – to pose for the new cover of Rolling Stone.

They didn’t stand next to each other (Audrina Patridge got between them, while Whitney Port stood on Conrad’s other side).

And, of course, Montag and Audrina are the hoochies in panties, while Conrad and Whitney opted for more demure lingerie.

The drama between the two is still brewing.

The two both hit the launch of the Scarlet HD TV Series bash in Los Angeles Monday night, and Montag couldn’t resist taking a swipe at her ex-BFF.

“I really pray for her,” Montag said.

Conrad’s bud, Lauren “Lo” Bosworth (who was also there), defended her pal.

“I wasn’t aware that Heidi was an especially religious gal,” she snapped. “But if she wants to pray, she can pray all she wants.”

When told that Montag is praying for her, Conrad rolled her eyes.

“That’s really nice of her,” she said before walking off.

Meow!!!

The Hills are alive with even more drama!

Topless shots of Audrina Patridge have hit the web. (See them here.)

Patridge, 22, says that she “took these photos years ago when I was just out of high school and beginning to model.

“I was young and very trusting of others and I didn’t know to protect myself,” she adds.

“It is a lesson learned, for myself, and hopefully for the young girls who look up to me.”

Audrina Patridge will take the stage alongside the Las Vegas Pussycat Dolls show inside Pure Nightclub on March 28 to celebrate the new season of The Hills.

Sources tell PEOPLE that Patridge will don the skimpy burlesque outfit that the Dolls are famous for to introduce the performers. Exactly what else she might do has yet to be determined, but previous celebrity hosts have sung, danced in a champagne glass, and swung from the ceiling on a swing.

Lauren Conrad has a new house and new puppy!

The Hills star, 22, writes on her MySpace blog:

“Last weekend, Lo (Lauren “Lo” Bosworth), Audrina and I moved into our new house. We love it!”

(The new roomies have been busy decorating: On Friday, they bought three shopping bags worth of merchandise at Crate and Barrel in The Grove shopping center in L.A.)

Conrad, who states on her blog her current mood is “tired,” continues: “On Monday, I got a puppy from the pound. She is the cutest puppy ever! Her name is Chloe. She is a lab/shepherd mix.

“I’m not getting much sleep because she thinks nighttime is play time! Ashes (my cat) is not thrilled with her, but I think they will become friends.”

The Hills returns to MTV March 24.

Season 3 of The Hills is coming back in less than a month.  Here’s a rundown of what you will see:
