The 27-year-old singer, who is apparently bring sued by former rap music mogul Suge Knight after his nightclub attack, is said to have launched into a row with PR Nicole Perna over his lack of magazine publicity.

According to a website, the row began over text messaging when Chris called her a do-nothing "b***h" before she fired back saying that she spent her time cleaning up his "sh*t".

It's claimed that the pair was discussing which magazine covers he wanted to feature on to promote his clothing line, Black Pyramid.

When Brown asked her to "get in the game" and secure high-end contracts, the PR wrote back, "Anna Wintour doesn't want to f*** with you. These editors don't want to f*** with you. The majority of my time is spent on damage control. I am constantly cleaning sh*t up and having your back."

Apparently, the argument ended with Chris looping in his manager to say: "Mike, this b***h got all the balls in the world talking to me but can't talk to the editors or anyone for that matter when they release bullsh*t in the press ... Send this b***h her termination (sic)."
