In June, 2 Chainz sent the internet into a frenzy when he posted a photo of him and Eminem with a caption that read, “Sooo this just happened... #marshalllikestrapmusic.” Its uncertain what the two were working on but during a recent interview with DJ Drama, 2 Chainz revealed they worked on on new music.

According to the Pretty Girls Like Trap Music rapper, it was Denaun Porter who reached out to 2 Chainz, trying to get the rapper to redo a hook and throw in some ad-libs for an Eminem track. Initially, 2 Chainz said he was reluctant to redo the hook, saying that he does his own hooks but eventually “humbled” himself and met up with Em.

After finally meeting up with the Detroit rapper, the two explored ways to improve the song before agreeing to a collaboration that would include a verse from 2 Chainz. While an Eminem has yet to be revealed officially, 2 Chainz said the song would appear on Em’s upcoming album.

Elsewhere in the interview, 2 Chainz also spoke about his recent get-together with Kanye West where he says JAY-Z was brought up. “JAY-Z came up. I knew that when I was going over there,” the rapper said. “Bro was like, ‘We still brothers…’ he had a couple things that was probably personal he want me to keep.”
