“Be Careful” what you say about her kids.

Cardi B deleted her Twitter after trolls brought up her children in response to the rapper not attending the 2022 Grammys on Sunday.

“I’m deleting my Twitter but On God I hate this f–kin dumbass fan base,” she tweeted before taking down her account. “You got the slow dumbasses dragging my kids all cause y’all though [sic] I was going to the Grammys and I didn’t the f–k ?”

Cardi, whose song “Up” was nominated for Best Rap Performance at the awards show, continued, “When the f–k I hinted I was going? just f–kin stupid I can’t I needs to protect myself.”

She seemed to be set off by multiple netizens who had tweeted about her two kids, whom she shares with her husband Offset.

“I bet yo (sic) son wouldn't like for you to be on your ass while teasing us fans and not ever dropping music,” one troll tweeted, to which Cardi harshly responded, “I hope your moms die.”

And when another user chimed in with a baseless claim that one of the “WAP” performer’s children is autistic, Cardi was left with no choice but to clear the air.

“@iamcardib do you kiss your @utistic child with that mouth?” the troll tweeted, leading Cardi to reply, “None of my kids are autistic…don’t project wat u got on my kids the f–k.”

In another tweet, she called her haters “so f–king dumb” and wrote that she really does not like them.

“SUCK MY D–K,” she concluded before disappearing from the social media platform.

While some people dragged Cardi for showing “disgusting behaviour” in the way that she called out her followers, others commended the artist for defending herself and her family.

The Bronx native went live on Instagram later on Sunday and asked, “Why would I show up for one nomination? … If you bring up my son, I wish the worst on you. I hate you.”

She also took a moment to clarify her response to the autism tweet, saying in part, “I never said there was nothing [sic] wrong with people who have [autism], but don’t put that on my f–king kid.”

Cardi won her first and only Grammy in 2019 for Best Rap Album for “Invasion of Privacy.”

The former “Love & Hip Hop: New York” star, 29, and Migos member Offset, 30, share 3-year-old daughter Kulture and a son, whom they welcomed in September 2021.
