Audrina Patridge is firing back at her ex-boyfriend who recently went off on The Hills star via his Twitter account, RadarOnline.com can report.

“He’s bitter because I broke up with him and he has a bad temper,” Audrina claimed as she was caught on camera during a day out with her girlfriends in Los Angeles.

As RadarOnline.com previously reported Audrina’s ex-flame, Australian BMX racer Corey Bohan, went on an expletive-filled rant about his former lady love Tweeting: "A girl that's told yes by everyone surrounding them grows up to be a heartless closed off insecure individual.”

In an earlier message, the tattooed tough guy lamented: "Time 2 pick up the pieces & stop being so sad! Some woman will always be empty & rotten from the inside out. U cant love a heartless woman."

And now Audrina is slamming him straight back.

“I was very honest and my feelings for him are gone. I will always care for him, but that’s it. If he wants to cuss out at me publicly and be like that…

“I’m not heartless…he’s doing that cause he’s bitter because I broke up with him.”
