Chris Brown slams management on Twitter

Singer Chris Brown has taken aim at his managers, branding them "incompetent" over a mix-up with his new music.

The Kiss Kiss star informed his Twitter.com fans on Monday night (27May13) that the release date of his upcoming single had been moved, and he launched into a rant against bosses at his management company.

In a series of posts, he writes, "My management is so incompetent at times that they don't communicate. So... Blame these wack (bad) n**gas for the release being moved. I'll keep yall (you all) posted. They got me looking crazy. Video/single will be released soon. Not gonna tell y'all (sic) an exact date becuz (because) I keep getting false info."

Brown did not specify which release was affected by the mix-up, but he recently filmed a music video in tribute to Aaliyah.

His song reportedly features a sample of Don't Think They Know, a previously-released track recorded by the late R&B singer, who died in 2001.
