New York rapper Cardi B knows how to troll with the most finesse. The hip-hop diva has new music reportedly gearing up to drop with her rap rival Nicki Minaj‘s ex-boyfriend.

According to reports, Cardi and Dreamchasers boss Meek Mill have a fresh collabo on deck.

Sources tell TMZ Cardi recently stepped into the studio with none other than Meek Mill to lay down some material that’ll be used in a forthcoming song. We’re told they cranked out hooks and verses — all of which is fair game for a final product that’s yet to be released. While we’re told the collab happened a few months ago, the timing is nothing short of less-than-perfect for Nicki … who’s in the middle of a good ol’ fashioned beef with Cardi. (TMZ)

On Nicki’s “Barbie Dreams” single, she jokingly talks about her ex-boyfriend Meek Milly low-key creepinging into her direct messages.

“Drake worth a hundred milli, always buying me sh*t/But I don’t know if the p*ssy wet or if he crying and sh*t/Meek still be in my DMs, I be having to duck him/”I used to pray for times like this.”/Face a** when I f*ck him” (“Barbie Dreams”)

Once the song went viral, Meek appeared to react to the must-hear song and most likely getting referenced.

Last year, the Philadelphia native revealed how much he loved Nicki during their two-year stint together.

“I always wanted Nicki my whole life … I bagged that. Of course breaking up with anybody you love is a loss, period. … I was too comfortable: I had Nicki, I’m getting all this money, living in Beverly Hills, getting high — there was nothing else I wanted at that point. Now it’s time to get this money. I’m [going to] show you who Meek Mill is.” (Power 99 FM)
