Chris Brown's Assault Lawsuit

Chris Brown is fighting to keep defamation claims out of his legal fight with ex-manager Mike G, claiming he was never served with the new version of the lawsuit.  

Mike G, who's suing under his legal name Michael Guirguis, filed a suit against Brown on June 23, claiming the rapper beat him up in a drug-fueled rage and then bragged about it.

"What Mike G assumed would be a run-of-the-mill conversation about the upcoming tour turned into Brown shutting Mike G alone into a room with him and brutally attacking him —punching him four times in the face and neck," states the complaint. "The assault was unprovoked and, regrettably, just another attack in Brown's long history of violent and abusive behavior."

That night, TMZ posted an Instagram video of Brown in which he calls Guirguis "Mr. Petty Pants" and says Guirguis only sued because Brown fired him for stealing money.

The next day, Guirguis' attorney Patty Glaser filed an amended complaint that beefed up the claims to include defamation.

Glaser argues Guirguis had not been fired, as his contract contained a provision requiring 30 days written notice of termination, and has never stolen money from Brown.

"Brown's acts were committed maliciously, oppressively, with an improper and evil motive, with knowledge of the falsity of his statements, and in conscious disregard of the rights of Mike G," Glaser writes. "Mike G already has suffered psychological and emotional injury, and pain and suffering, all of a serious and permanent nature, at the hands of Brown, and Brown's defamatory statements only add to this." 

Brown is contesting the amended complaint on the grounds that he was never served with it. While Brown was home at the time the process server claims to have delivered the documents to him personally, he says he never saw or spoke to any such person. 

Further, Brown says his home is surrounded by a security fence that requires either a code or permission from someone inside to enter and the premises are monitored by video cameras. In his declaration to the court, Brown says the video does not show a process server approaching his gate at the time the papers were purportedly delivered.

"[N]o one present at the residence with Brown was approached by anyone to serve process on Brown," states a motion to quash filed by the rapper's attorney Susan Gutierrez. "No copies of the Legal Papers were ever found at the residence or outside the front gate. And to this day, Brown has never seen, received, or reviewed the Legal Papers."

A hearing is set for November 29.
