Booze before bubbles brawl

CARDI B and husband Offset had been drinking heavily during a wild night out before he threw punches in the crowd at a Miami strip club early Friday morning, Page Six is told.

The Migos rapper caused havoc by swinging at a reveler whom he seemed to suspect of splashing his wife with champagne.

But we’re told that hours earlier, Cardi arrived at Liv nightclub at Fontainebleau at 2:30 a.m., and that her husband showed up to join her a little later.

A spy tells us the “Bodak Yellow” rapper “was drinking the entire time” she was at the club.

“She had a Corona bottle with her before she performed and then was drinking onstage,” says an attendee. “She was raising her glass and asking everyone [in the crowd] to ‘have a drink with’ her.”

One spy describes her drinking as “nonstop.” Another said she even seemed too drunk to finish her set, but club sources insisted that she finished all the songs that she’d been scheduled to perform.

While one attendee said she seemed to be stumbling, another tells us the problem was actually her sky-high heels. “It’s the Cardi shuffle,” they explained.

Meanwhile, when Offset performed their song “Clout” with her, several witnesses tell us she simulated oral sex on him. “It went on for a while,” said an audience member, though another contended she was just kneeling because her feet hurt.

We’re told the pair then left immediately to head to fully nude strip joint Booby Trap on the River, which, according to its Web site, offers a $4.95 14-ounce steak special.

TMZ published a video that shows the couple standing near a dancer’s pole as Cardi appears to get splashed with champagne. Offset then scans the crowd for the supposed offender and swings his fist into the audience. He was reportedly pulled off by security, and they left immediately after the brawl.
