Audrina Patridge just can't stay away from Corey Bohan.
Even though he called her a "heartless closed off insecure individual" on Twitter and she told a TMZ cameraman he was bitter over their April split, the two were spotted together again yesterday in Griffith Park in Los Angeles -- kissing, holding hands and having a picnic for the cameras.
This is Audrina's second time going back to Corey -- who she dated from 2008-2009 and again after her 2010 breakup with Ryan Cabrera.
