They reconnected for a summer fling, and now Audrina Patridge
and her BMX racer beau Corey Bohan have re-split up.
"They broke up amicably a few weeks ago and are still friendly," a source tells PEOPLE. "It's mainly to do with their busy schedules. She's constantly filming, and he spends six months out of the year in his native Australia. She's single, and happy!"
The pair dated for several months last year, got back together
in June in Las Vegas and were together at least until August when they were spotted poolside
at Hollywood Roosevelt Hotel's Tropicana Bar.
Patridge, 24, who appeared in the recent horror/comedy Sorority Row
, also has been linked at various times with Hills
stars Justin Bobby and Brody Jenner, Star Trek
's Chris Pine and CMA Collective partner Tal Cooperman.
