Looks like they’re on again!
After several weeks of partying in Palm Beach, Fla., and Mexico together, Audrina Patridge has split from her polo player boyfriend Nic Roldan and started dating ex-boyfriend Corey Bohan again, a source tells PEOPLE.
“They really had a blast together but she has started seeing her ex-boyfriend Corey Bohan,” the source says. “Nic has moved on.”
Patridge, 26, who stars in VH1’s Audrina, had asked Roldan, 28, to join her in New York when she was promoting the show last month, then again for the Kentucky Derby. But things changed in her life, and the dates were broken.
