Chris Brown has been accused of beating up his manager.

The 27-year-old singer has been sued by Mike G (real name Michael Guirguis), who claims that he had to be taken to hospital last month after Chris "brutally attacked him with repeated punches to the face and neck".

Mike G's attorney, Patty Glaser, told TMZ: "We did everything we could to resolve this in a non-public way to avoid damage to Chris Brown. Regrettably, as outlined in our complaint, Chris Brown has proven to be his own worst enemy."

The manager's lawsuit, obtained by TMZ, goes on to claim that after the alleged beating, Chris started mocking him on social media and told people "working on his tour, if they got out of line he'd beat them just like he beat Mike G".

After TMZ reported the allegation, Chris Brown posted a nonsensical Instagram video statement in response.

"Don't nobody come out clean in the s*** throwing contest," Brown said in the video.

"And I could through a big piece of s***."

Brown then went on to thank his fans for supporting him.

Chris hired Mike G, owner of Nitevision Management, in 2012 to reportedly rehabilitate his public image after pleading guilty to assaulting Rihanna in 2009.

Mike's contact details are currently still listed on Chris' website.

This case comes just one month after Chris was accused of stamping on a man's head.

The She Ain't You hitmaker reportedly trod on Malek Mokrani's face at a club appearance held at Gotha nightclub during the Cannes Film Festival on May 18.

The alleged assault came after footage surfaced from the event with the singer songwriter moving away from a large group of people before taking a swing at Malek, however it is unknown whether Malek started the fight.

The concert goer was treated for head and neck pain and suffered severe bruising to his face.

Malek was also pictured wearing a neck brace after the incident.

And recently the Fine China singer's former lover Nia Guzman had claimed he was unfit to care for their two-year-old daughter without strict supervision and had asked a court to appoint a monitor and reduce the amount of time the star was allowed to spend with the little girl.

However, earlier this year, a judge denied the request and kept the existing arrangement for joint legal and physical custody - which sees Chris care for his daughter 12 days a month - of the youngster in place.
