Audrina Patridge on Kristin Cavallari: "I Don't Like Her"

[UsWeekly] - Move over, Lauren and Heidi.

A new feud has emerged on The Hills: Audrina Patridge vs. Kristin Cavallari.

"I don't like her," Patridge confessed Thursday on Ryan Seacrest's KIIS-FM radio show.

She confirmed the two had a fight the first day of filming bonus episodes of the MTV show (it has been rumored that Cavallari has been pursuing Patridge's ex, Justin Bobby).

Patridge was mum on what went down, but told Seacrest, "When someone gets in my face, I have to defend myself. And, you guys, I mean, I can't say much. They'll show it, but I mean, all I have to say is, it's really pathetic and desperate what people will do when the cameras are around."

"It was my birthday, and I was like, Oh, my God. Is this what we're going to have to deal with?'" she added.

Patridge wouldn't open up about her recent fling with Star Trek hottie Chris Pine.

Us Weekly reported that the two met at ShoWest in Las Vegas in early April. On May 15, she was spotted leaving his L.A. apartment building.

"There's always speculation of anyone I hang out with or anything I do," a coy Patridge told Seacrest.

Pressed for more, she replied, "My lips are sealed."

Still, she said, "From Justin Bobby, I think any guy is an upgrade. I mean, I've learned so much since that relationship."

Audrina and Justin-Bobby Get Into Screaming Match

Whilst we'd prefer to see Heidi and Spencer having an enormous bust-up, unfortunately it was another Hills couple at war last night. TMZ cameras caught the MTV crew filming for an upcoming episode of the show outside Opera - when outside the club appeared Audrina Partridge and sometimes-boyfriend Justin "Bobby" Brescia, and continued to have a huge argument. Justin soon disappears into the shadows after Audrina shows him the double-barrel salute, screaming, "He doesn't even have the balls to come and talk to me!"

Retreating to the parking lot with BFF and roommate Lauren Conrad, the MTV crew sprinted after Audrina, obviously ecstatic that something genuinely happened for once!

Audrina on Justin 'Bobby': "He's So Cute!"

The Hills star and new-BFF to Lauren Conrad, Audrina Partridge, has rubbished surfacing skepticalities fans have raised over her revived relationship with ex-boyfriend Justin 'Bobby' Brescia.

Audrina, 22, who works at Epic Records and is roomie to LC, said, "Of course we have our feuds and everything, but it's fun having him part of the show...he is so cute!"

In the last few episodes of The Hills, LC hasn't looked too enamoured by Justin and has been seen warning Audrina against rekindling their former flame. Other friends of Audrina's, however, say they're convinced that the 25-year-old hairstylist might actually be the one for her. "The core people around Audrina's life know what Justin means to her," says a friend. "It's not like he's just pursuing her to be on the show...he is dealing with the show so he can continue to be a part of her life," said a friend. Audrina herself confirmed this saying, "He is so not used to having the cameras around...he hates it, but he does it for me."

In that case, it must be love, right?
