Cardi B is being sued for assault and battery after she allegedly struck a woman with a microphone during her performance in Las Vegas two years ago.

The woman — identified as Jane Doe — claims in the lawsuit that the “I Like It” rapper had asked the audience at Drai’s Beachclub to throw water at her to help her cool off, TMZ reported Wednesday.

Doe alleges that several people answered the pop star’s request, but Cardi chucked the mic at her when she did so.

The microphone, meanwhile, was auctioned off for $99,000, which Doe claims “exacerbated [her] emotional distress.”

The “Up” singer, 32, was not charged when the incident occurred.

Reps for Cardi weren’t immediately available to Page Six for comment.

Shortly before Cardi lost her cool, she was seen in a video encouraging the crowd to “splash” water “in [her] p—y.”

“That s–t feels good,” she said, as the DJ encouraged fans to “splash her down.”

Seconds later, the woman, who accused the hitmaker of assault, threw a cup full of water at Cardi.

After the mic was thrown, security escorted the woman out of the venue.

Cardi later addressed her heated moment, saying, “I don’t want to look [like] that ghetto bitch.”

“I said splash my p—y, not my face, bitch.”

Cardi hasn’t shied away from calling out fans in the past, including after they accused her of copying Nicki Minaj’s style.

She also told fans to “shut the f–k up” after several claimed that she got back together with her estranged husband, Offset, in 2023.

The “WAP” singer officially pulled the plug on her marriage with the fellow rapper in August 2024, and has since moved on with Stefon Diggs.
