Chris Brown is in hot water for allegedly raising his hands again. 

According to court documents obtained by E! News, Michael Guirguis, also known as Mike G of Nitevision Management, filed a lawsuit against the Grammy winner for assault, battery, false imprisonment, intentional infliction of emotional distress, breach of contract and breach of implied covenant of good faith and fair dealing after he alleges the singer "brutally" attacked him in early May before embarking on his European tour. 

The manager claims Brown was in a "drug-fueled" rage when he attacked him in a room and punched him four times in the face and neck—injuries that ultimately led to an emergency room visit. The documents state that the singer allegedly took to social media afterward, "boasting" to his friends about the incident. 

Guirguis claims in the documents that he was hired by the Grammy winner to "repair his reputation" after Brown pleaded guilty to assaulting his then-girlfriend Rihannain 2009.

After his manager filed the suit, Brown took to Instagram to comment on the situation.

"I fired them because they're stealing money," he claimed in response. "You're stealing money pal, so you're mad because you're no longer existent…God Bless you. Wish you the best of luck."

"We saw Chris Brown's response [to the complaint Mike G filed] that he posted on social media," Patty Glaser, Mike's attorney, told E! News exclusively. "[Chris] said he claims he fired Mike G. because he stole from him. That is unequivocally untrue and shameful and we will be amending our complaint to allege defamation."

While Mike G has not commented separately from the suit, he did take to Twitter in early June with a cryptic message regarding work. 

"The ability to walk away is your best tool in any business practice," his message read

Meanwhile, Brown has most recently been embroiled in a custody battle with Nia Guzman over their only child, daughter Royalty. While he was ultimately granted 12 unsupervised days a month with the toddler, Guzman publicly claimed she wanted a nanny present for their visits.

"He knows he cannot do it on his own. She's only two, and she's a lot of work," she told Latina magazine. "I just wanted a nanny in place when she was with him, and it be agreed upon."

The comments launched a digital feud between the two in the comments section of Instagram. "I DO AMAZING WITH MY DAUGHTER! Just LIKE IM PAYING FOR THE BDAY PARTY YOU ARE THROWING! 30k!!!!!!" he said.

"I SIMPLY WANTED A MONITOR FOR YOUR CERTAIN ADDICTIONS...YOU CHOSE ME," she replied. "YOU CHOSE TO LAY WITH ME."
