Kristin Cavallari disses LC's workout ethic, claims she'd kick her a** (VIDEO)

Leaving the gym last week, Kristin Cavallari was caught by TMZ.com and asked if she was into UFC - Specifically asking if she would KO former Hills star Lauren Conrad in a cage fight.

After claiming she'd kick LC's a**, says TMZ, the star then dissed LC's workout ethic.

"I like watching those fights," she said before TMZ asked her if LC and her met up in a cage, "Who would win?"

"Who do you think would win?" Cavallari catted back. "Me, I'm the one working out."

The gossip channel caught the Hills' self-proclaimed "bitchy one" leaving the gym "dripping wet" after a "hard class".

Earlier this month, Cavallari was shutterbugged leaving her pilates class at Burn 60 by X17.com.

"That was my first Pilates class in a longtime," Cavallari told the pappo of her 30-day hiatus from the practice. "My abs are killing me." 

Addding, "I'm too lazy to do anything more. It was an hour class." 

Cavallari, who tries to do Pilates at least three times a week, also enjoys kickboxing and lightweight resistance training but she said in her interview with X17 her workouts don't "happen that often".

When X17 asked about her workout routine, she said that she wasn't vey strict about going, but K.Cav is often spotted fleeing from one sweat sesion to the next.

Quoting the LA Times blog, the star has struggled for the past four years, even saying her work had become so increasingly overwhelming she was experiencing weight loss, headaches and low energy.

"She hosted a show on the now-defunct UPN about party planning that was canceled after two episodes," says the LA Times of The Hills star's recent history. "Earlier this year, she played alongside Rob Schneider in a high school comedy that went straight to DVD."

Adding, "Now, Cavallari has landed a role where she knows all eyes will be on her." The Times quoted the star as saying, "I pretty much do anything they have me do because I don't care."

But maybe Cavallari who says she's lazy and doesn't care, really isn't and really does. What do you think - Is Cavallari  feeling The Hills pressure?
