Newly Single Audrina to Kristin: Have a Heart!

After starting off on a very wrong foot with The Hills newbie Kristin Cavallari, Audrina Patridge can’t sit back any longer and watch the man-eating blonde steal away her on-again, off-again boyfriend, Justin Brescia, aka Justin Bobby, without any remorse.

Audrina believes that Justin and Kristin are “just trying to make a good show, start drama, and trying to hype it up and I understand that,” the saucy brunette told OK! exclusively at the Pepsi 500 Celebration in Hollywood on Wednesday.

"But at the same time, have a heart," she adds.

Regardless of whether or not Kristen will actually listen to Audrina’s wise words, the soon-to-be ex-cast member of The Hills is planning on doing her own reality show with Mark Burnett in December.

”It’s hard to sit back and try to go film with her and try to be friends with her when someone is bashing you like that," Audrina explains of Kristen.

Audrina is turning a new page and leaving all of her recent rivalries and romances, including Justin Bobby and BMX rider Corey Bohan behind.

“Corey and I are not together anymore and we actually broke up a few weeks ago,” the reality star dishes to OK! about her ex- Australian boy toy. “I couldn’t give him 110 percent like he wanted and it wasn’t fair so I decided to break it off.”

As for JB and Kristen’s newfound fling? Audrina can only wish them well, as she tells OK!, “I accepted it and they should go for it. Have fun!”
