Cardi B returned to Instagram after a short break because she got acquainted with Ariana Grance.
The 26-year-old has disabled her account after being targeted by trolls after her Grammy victory on Sunday.
She was the first solo bitch to win the best rap album thanks to her debut Invasion Of Privacy, but she was annoyed at the fans who said it was undeserved.
Pop singer Ariana Grande was the most famous objection to Cardi B's victory. He was posted on Twitter after her ex-boyfriend Mac Miller was overlooked after his death.
Ariana tweeted "garbage" first, followed by "f ***" and then "bull ****" in a third tweet.
During the long chatter, Cardi said, "I worked my ass off, locked myself in the gym for three months, did not fall asleep in my own bed, sometimes four days in a row – pregnant!"
After Cardi B posted an explosively filled video, she deleted her Instagram.
However, her absence proved fleeting, and she returned to the social media site Wednesday with news of a new track with Bruno Mars.
She said, "Okay, I'm back from retirement to announce that on Friday at midnight a brand new song with @brunomars will be released."
Along with the message, Cardi B shared a picture accompanying the new song, showing that she and Mars were facing each other.
Born in Bronx, Cardi B, whose real name is Belcalis Almanzar, won Grammy's best rap album, ahead of genre heavyweights Pusha T and Travis Scott, both nominated for Daytona and Astroworld.
Swimming by the late Mac Miller and Victory Lap of Nipsey Hussle were also nominated.
Invasion Of Privacy, released last April, includes the hit songs Bodak Yellow, Be Careful and I Like It.
During her acceptance speech, Cardi B thanked her husband, Migos Rapper Offset, and the couple's seven-month-old, Kulture.
