Did Cardi B fart during her Grammys ‘WAP’ performance?

Megan Thee Stallion walked away with three Grammys for her remix of “Savage” with Beyoncé — but it was “WAP” collaborator Cardi B who gave her a moment to remember during their electrifying, X-rated performance.

“Slang me so hard almost made me fart,” the “Up” rapper tweeted on Monday night, in response to a fan who praised the women for their kinky choreography.

Their wild routine — a mash-up of the hip-hop divas’ hottest singles of last year — included one deftly executed move in which Megan, crouched on all-fours, uses her legs to flip the belly-up Cardi onto her stomach.

So swift was the turn that even Cardi appeared shocked at that moment, according to fans who zeroed-in on the bold stunt.

Some 96,000 boosted the hilarious tweet with likes on Twitter, including an inspired response from “American Pickle” actor, filmmaker and cannabis lifestyle purveyor Seth Rogen.

“As long as it wasn’t a WAF,” said Rogen — suggesting the play-on-words: wet a - - fart. His response alone drew more than 72,000 likes.

Megan, 26, took home Grammys in the categories of Best New Artist, Rap Song and Rap Performance. Meanwhile, Cardi B was left off the nominations list this year — in the interest of submitting “WAP” next year as part of the 28-year-old rapper’s forthcoming album.

But there’s plenty for her to celebrate, such as her 2018 debut single “Bodak Yellow” officially surpassing the 10 million units sold mark, making her the first female rapper to go diamond for a single track, according to the Recording Industry Association of America. “WAP” was also recently certified 5-times platinum.
