Singer Monica stopped her show in Detroit to defend a woman who was being assaulted in the audience.
Video from Saturday night’s Riverfront Music Festival showed the “Boy Is Mine” singer jumping off the stage to confront the male attacker.
Fans cheered as security guards followed Monica through the crowd.
“Don’t hit no fucking lady like that,” he warned before the man was kicked out of the festival.
After the incident, Monica returned to the stage and apologized to the fans for losing her temper.
“That shit turned me on,” he said. “I saw him punch that lady in the face, I lost my temper. I apologize. I apologize from the bottom of my heart.”
Still a little hot, the 90s hitmaker admitted: “I was going to call [his] your ass with that shitty microphone.”
Monica addressed the fight in a comment on The Shade Room’s Instagram on Sunday.
“I apologized there and I apologize here for my actions, but no one would act!” she wrote “I was so excited, I looked and it was like I didn’t even know him!”
“It felt like it was all about space during a packed concert!” she continued. “He punched her with all his might! My intentions were to stop him from hitting her again and he didn’t! I called for help, it fell on deaf ears! It was like watching my mother or an aunt get assaulted!! This woman was over 50 years old, I wish her well!”

In a statement to CBS News, Riverfront Music Festival spokesman Andrus Macdonald praised Monica for taking action.
“We would like to extend our sincere thanks to Monica for her bravery and decisive intervention during an unfortunate incident at our Festival,” he said. “His actions demonstrated a commitment to the safety and respect of his fans, reinforcing our belief that he is not only an extraordinary talent, but also an extraordinary person.”
He went on to say that organizers were “truly saddened that an event meant to bring joy and unity to our community was marred by an act of violence” and are currently working with law enforcement to hold the attacker accountable.
Surprisingly, this wasn’t even Monica’s first foray into crowd management this year.
During a concert in Washington, DC in April, the star told rowdy audience members to “shut that shit down” or take their problems outside.
