Cardi B has been sighted dancing at poolside the same day she was named a suspect in her microphone-tossing case.

Cardi posted a video Monday, which shows her and hubby, Offset, having a swell time on the rooftop of what appears to be a Vegas hotel.

Both rappers are in bathing suits, Cardi is twerking like crazy in the pool as Offset wildly dances around her.

Cardi was named as the suspect in a battery case after she hurled a mic into the crowd at her Vegas concert Saturday, hitting two people.

Video captured the moment someone splashed Cardi with a drink while she was onstage at Drai's Nightclub, after she encouraged the audience to cool her off with water in the extreme heat.

Cardi clearly did not approve of the way the liquid drenched her body, prompting her to throw the mic, which first struck the drink thrower and then flew and hit a woman standing nearby.

The woman later filed for battery.
