It looks like Mischa Barton has found her self single once again after splitting from boyfriend Cisco Adler for the second time in about a month.

Barton, known best for her role as Marissa Cooper on the hit show The O.C., has reportedly broken up with Adler after he complained that she was too much of a partier.Britain's Daily Star newspaper reported that Barton wasn't too happy to hear from Adler that he thought she spent too much time hanging out with her close friend Nicole Ritchie. So, she dumped him.

This split comes on the heels of a fight they had at the Beverly Hill Hotel just last month that also caused them to break it off.At that time, friends claimed that the couple had a hard time staying together because their romance was under too much intense public interest.

Although Barton was said to have found comfort by turning to Jake Gyllenhaal, she and Adler did reconcile. We'll see if they will reconcile again, or if they will go their separate ways.
