Her rapper beau Offset proposed to her in October with an eight carat $500,000 diamond ring.

And Cardi B, 25, and her fiance, 26, pretended to get intimate on Instagram live as a joke, according to Page Six.

After fans thought it was real, the rapper took to her Instagram stories to clarify and said: ‘I was fully clothes on live. I was not f****n on live. Yaaa can’t be that slow.’

The Instagram live clip, which surfaced on a Twitter page called Worldstarhiphop, shows a full clothed Cardi B looking into the camera as Offset thrusts behind her.

She says in the clip: ‘I don’t got no more in me left. You gotta give a whole hour…’

Page Six adds that before their pretend session Cardi talks about her mother.

TMZ confirmed that the Instagram Live was fake; her rep told the website it wasn’t real.

Her joke comes after the Bodak Yellow singer was hit with claims of appearing in a sex tape.

A video leaked onto the Internet on Friday claiming to show the singer dancing in the nude, according to Page Six.

The video was leaked on the same day as the release of her latest single, Bartier Cardi.

She spoke out about the claims on her Twitter account on Monday and said: ‘People keep posting the nude videos of me like if I wasn’t a stripper before. You know there’s videos of me stripping with my t*****s and a*s out on YouTube already right?’

Adding: ‘Anyways I know I know I got a nice body right.’

Fans also quickly jumped to Cardi’s defense on social media.

‘In the video, one can see Cardi B smiling, laughing, twerking and bending over for the camera,’ Page Six wrote.

The publication reported that the person who had posted the short clip shared on Friday called it a ‘preview’ to a more explicit version.

DailyMail.com have contacted Cardi B’s representatives for comment and have yet to hear back.

One Twitter user asked, ‘Why are people leaking nude videos of Cardi B? She used to be a stripper, her naked body isn’t a secret or a scandal. Y’all won’t let anyone successful keep their past in the past.’

Another fan admitted that the leaked video was released in poor taste as her second single Bartier Cardi hit iTunes the same day.

‘You gotta be next level lame to post a video of cardi b nude twerkin on the night she trying to establish herself as a label artist,’ one Twitter fan wrote.

One Twitter user chose a gif of Wendy Williams shaking her head, with the comment, ‘Trying to figure out why there’s a nude video of Cardi B on the timeline this morning.’

Cardi – real name Belcalis Almanzar – was a former Bronx-based stripper with a massive social media following.

The Love & Hip Hop: New York star shot to fame earlier this year with her hit song Bodak Yellow, which also won Single of the Year at the BET Awards.

Not only did the song go triple-platinum, but it also knocked Taylor Swift’s coveted Look What You Made Me Do off the top of the Billboard Hot 100; She was also nominated for two Grammy Awards.
