The saga continues… Chris Brown and Frank Ocean allegedly reignited their former feud between each other last night during an apparent fight that occurred at a Los Angeles recording studio.

The two previously exchanged words on Twitter in 2011 and eventually made peace. But they supposedly took things further last night when they crossed paths. According to Rolling Stone (via TMZ):

Brown’s people blamed the altercation on Ocean, saying that Ocean and his entourage had blocked Brown from leaving Westlake Studio, where Brown had been listening to one of the artists he represents. After exchanging words, Brown allegedly went to shake Ocean’s hand, which sparked a brawl between the singers and their crews.

Brown had left the parking lot by the time police arrived, but Ocean talked to the responding officers. Police said the investigation is ongoing and they would contact Brown later.

Now, E! News is reporting that Chris is being investigated for assaulting someone at the scene.

Frank took to Twitter after the altercation and tweeted the following:

And Chris posted a photo on Instagram, defending himself from circulating reports.

“Working on my album. Not working on negativity. Focus on feeding ya family. Bullshit will forever be in the shadows.”
