The reality TV star has reportedly ended her brief romance with polo player Nic Roldan and rekindled her relationship with BMX racer Corey Bohan, who she split from in March after around two years of dating.
A source close to Nic told People: "They really had a blast together but she has started seeing her ex-boyfriend Corey Bohan. Nic has moved on.
"Audrina and Nic had something going but it was bad timing as she is still interested in her old boyfriend."
News of Audrina and Corey`s reconciliation may come as a shock as the 26-year-old beauty said she no longer had feelings for him.
Speaking after Corey branded her "heartless and insecure" in a twitter rant, Audrina 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...
"I`m not heartless... he`s doing that because 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)"
