Parking spaces are serious real estate in Los Angeles -- but enough to cause two musicians to come to blows? The answer, apparently, is yes, as Frank Ocean and fellow R&B star Chris Brown put up their dukes yesterday (Jan. 27) over a studio parking spot.

Police were summoned to L.A.'s Westlake Recording studio after the two men used their fists to solve the issue, according to TMZ.

Ocean tweeted, "Got jumped by Chris and a couple of guys. Lol. I only wish everest was there." While that made the incident seem less than serious, the singer also posted: "Cut my hand now I can't play with two hands at the grammys."

Now that's a problem.

Brown's sources, meanwhile, claim that Ocean instigated the brawl, saying, "This is my studio, this is my parking spot." Breezy's witnesses also allege that someone in Ocean's crew "then attacked Brown when he went to shake hands with Ocean."

Sounds like a messy case of "he said, he said." The two have something of an antagonistic history, as Brown was accused of hurling a homophobic slur at Ocean, who revealed last year that he'd had a same-sex love affair.
