The Mariah Carey & Cardi B collaboration hasn't come into fruition yet.
Cardi B is undoubtedly one of the hottest rappers in the game right now. She could have a number one record with Maroon 5 then turn around and collaborate with Meek Mill on a banger. While speaking to Andy Cohen, Mariah Carey mentioned that she wanted to collaborate with Lil Kim and Cardi B on the same song. However, she did say that "if nobody puts it together, it’s not going to happen.” Unfortunately, it doesn't seem a collaboration with Mariah Carey and Cardi B isn't coming soon.
During an interview with Extra, Cardi B revealed that she and Mariah Carey have not been in the studio together. However, she didn't say that it wasn't possible that it won't happen in the future -- it's just that her schedule is too tight right now.
"It is not in the works," she revealed. "It would be nice if it could be in the works. I [have] just been so busy that I haven't even had time to do my own songs."
Cardi B is currently prepping the release of the Invasion Of Privacy deluxe edition. The rapper previously released the single "Money" and recently previewed a snippet of a new song that seems to be titled, "Press." Both songs are expected to be included on the deluxe edition of the album which is reportedly due out at the end of January.
