FORT WORTH, Texas — A lawsuit filed Sunday alleges R&B singer Chris Brown and his entourage beat four men after his Saturday night concert in Fort Worth. Brown is named alongside Texas rappers Yella Beezy and Hoodboss (a.k.

a. Hoodybaby), UK rapper Sinko Ceej and entertainment conglomerate Live Nation as defendants in the lawsuit. The lawsuit claims the assault happened following Brown's concert at Dickies Arena in Fort Worth on Saturday night.

The court filing alleges that the attack was unprovoked, and involved Brown and his entourage surrounding the plaintiffs, then throwing chairs at them, kicking them, stomping them and beating them. The four men listed as plaintiffs in the suit are seeking retribution from the men who allegedly beat them as well as from Live Nation, the company that promoted the event. The plaintiffs, who are being represented by prominent Texas attorney Tony Buzbee, are seeking $50 million in compensatory and punitive damages.

Buzbee has previously litigated high-profile cases against NFL quarterback Deshaun Watson, rapper Travis Scott and oil and gas giant BP. He was also the lead attorney representing Texas Attorney General Ken Paxton in his impeachment trial . Buzbee issued a statement regarding the case via his Instagram account on Sunday morning.

"We filed suit last night alleging that, on Saturday night in Ft. Worth, entertainer Chris Brown, along with his entourage, attacked and brutally beat several men who had just attended his concert," Buzb.
