Cardi B has threatened to sue a prank caller who allegedly sent Child Protective Services to her house while she is in hospital.

The rapper, 32, who welcomed her third child last month, slammed the caller for ‘messing with my kids’ and said she had her sister or estranged husband Offset would ‘beat them up’ if they found them in a video shared Tuesday.

Speaking from her hospital bed, as she is treated for a currently unknown condition, the star said: ‘So I wanna make this very f***ing clear, and I can’t even breathe right now.

‘Motherf***ers have taken s**t too f***ing far when you mess with my f***ing kids.

‘For the Child Protective Services to come to my f***ing house? Not my house, my gated mansion at 11 p.m. while my children are sleeping because there’s an anonymous call… that my kids have been getting abused and beaten. Are you f***ing dumb?’ 

We don’t play that s**t. My kids live great. My kids have never been touched, never gotten hit no matter how annoying they are. Don’t you ever in your f**king life play with my motherhood or my ex-husband’s fatherhood.’

The star continued: ‘We’re the only colored people in my neighborhood completely and for motherf***ers to pop up in my house with cops and child protective services because you motherf***ers wanna do an anonymous call involving my children.

‘I promise you this, I’m gonna sue CPS for f***ing coming to my house at whatever the f*** time it is. [I will sue] the person that did this anonymous call.’

Addressing the caller directly, she said: ‘If you’re a boy, my baby father is gonna beat you the f**k up. If you’re a woman, me and Hennessy are gonna beat you the f**k up because you playing with my motherf*****g kids.’

‘Not everything is a f***ing joke. Not everything is a f***ing prank.’

Cardi recently went on the offensive during an Instagram Live after Offset accused her of cheating on him while she was pregnant.

‘Nothing surprises me anymore. You’ve done it all, so I don’t care,’ the Grammy winner.

But then, she pounced on Offset with some hard-hitting comments, while not naming him directly.

‘Thank you for my kids, though. All three of them, I don’t regret none of them. But I regret you,’ the New York City native said with obvious emotion to her words.

The estranged couple first started dating back in February 2017, when Offset took her to see Super Bowl LV between the New England Patriots and the Atlanta Falcons at NRG Stadium, Houston, Texas.

After started off huge with expensive Super Bowl tickets, the rumors of their romance began circulating all the way through until their secret marriage in September of that same year.

Over the course of the next six-plus-years the pair had an on again, off again relationship several times over that typically included lots of hard-hitting comments on social media and in interviews.

During that time of back-and-forth between the duo welcomed two children to the world: daughter Kulture, six, and son Wave, three.

But apparently the breaking point for Cardi came on July 31 when she officially filed for divorce from Offset (born Kiari Kendrell Cephus), 32.

But then, just one day later, Cardi went public to announce she was pregnant with her third child with Offset, a daughter who they have yet to reveal her name. 

Cardi B has already petitioned the court for full custody of her three kids with Offset.
