Audrina Patridge's ex is 'bitter'

Audrina Patridge thinks her ex-boyfriend lashed out at her because he is "bitter".

The former 'Hills' star parted ways with Corey Bohan two weeks ago after being involved with him since 2009, leading the BMX racer to call her "insecure" and "heartless" on twitter.

However, the beauty - who has reportedly moved on with Prince Harry's close friend, polo player Nic Roldan - has hit back, saying the tirade was a result of Corey's "bad temper" and insists she has always been "honest" with him.

She said: "He's bitter because I broke up with him and he has a bad temper."

"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..."

The brunette added in a video filmed by TMZ: "I'm not heartless... he's doing that cause he's bitter because I broke up with him."

Corey wrote in the twitter post, which has since been removed: "A girl that's told yes by everyone surrounding them grows up to be a heartless closed off insecure individual. 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. (sic)"

He later added: "Life is easy without insecurities :) my mates are the best. Love u guys!!!"

"It's funny when life puts u in the right spot when u don't even expect it. Cause when u have the info n it's perfect it's just so easy. (sic)"
