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 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.
