Frank Ocean, Chris Brown and their respective entourages engaged in a brawl Sunday night, though further details remain unclear.
TMZ initially reported that the fight occurred in the parking lot of a Los Angeles recording studio, when Ocean blocked Brown from pulling out of a spot. Sources close to Brown told the site that the singer attempted to shake Ocean’s hand, which led to pushing between the groups and eventually a brawl.
Later, the reported that witnesses said Brown threw the first punch.
Brown had left the scene by the time police arrived, but Ocean was still there. Authorities are investigating the situation, though TMZ says neither side wants to press charges.
Ocean later tweeted about the fight, saying that he was jumped by Brown and several others and that he cut his finger and would be unable to perform with two hands at the Grammys on Feb. 10.
The pair have feuded before. In 2011, Ocean took exception when Brown said "I f— with Frank Ocean" and compared him to songwriters James Fauntleroy and Kevin Cossom. He fired back, saying Brown was reminiscent of R&B acts Sisqo and the late Ike Turner.
Brown engaged in a much publicized fight with rapper Drake at a New York nightclub in June.
