Chris Brown has been sued for $50 million stemming from an incident that took place backstage at one of his concerts last Friday.

The plaintiffs—Larry Parker, Joseph Lewis, Charles Bush, and DaMarcus Powell—filed their lawsuit in a Texas court on Monday, July 22. They are seeking at least $50 million in damages. In addition to the payment, the four plaintiffs are asking for a temporary restraining order against all defendants.

According to the complaint, which was first reported by TMZ, Brown and his crew severely beat the plaintiffs following the singer’s performance as part of his 11:11 Tour at Dickies Arena in Ft. Worth, Texas this past Friday. The four men were invited backstage after the set to meet Brown, who showed up 30 minutes later than anticipated.
