Did Chris Brown Jump Frank Ocean?

Just as Chris Brown was attempting to rehabilitate his rep (watch his video to end HIV stigma), he goes and does something stupid again. TMZ broke the news that there was an alleged fight outside a Los Angeles recording studio on Sunday between him and R&B singer Frank Ocean.

According to sources, witnesses told investigating deputies that the "fight was over a parking space--and that Brown threw the first punch." But, of course, reports are differing, with other witnesses telling TMZ that someone attacked Chris as he tried to shake Ocean's hand... Sheesh.

Ocean, who allegedly cut his finger in the fight, took to Twitter following the melee: "got jumped by chris and a couple guys. lol. i only wish everest was there," he wrote. Everest is the name of the singer's Bernese mountain dog. He also wrote: "cut my finger now I can't play w two hands at the grammys."

Investigations continue...
