The 39-year-old rapper is set to join forces with the 34-year-old vocalist on a new track, which has yet to be named, but the 'Good Drank' musician believes the track and recording a single with the artist, which will feature on his 'Pretty Girls Like Trap Music' album, will cause him a few issues.

Alongside a picture of the 'Anaconda' hitmaker's name in pink neon lights, which was posted on his Instagram account, he wrote: "I don't talk much but my song with her is goin to be a problem #prettygirlsliketrapmusic (sic)."

Alongside a picture of Nicki and 2 Chainz in front of her illuminated name, which was also share don the photo-sharing site, she wrote: "All Ima say is YIKES (sic)."

Meanwhile, the Trinidad and Tobago-born star has taken to social media to uncover a few home truths about her music.

And the artist has revealed when she pens a new record, she always writes it in a "comfortable key" to suit her vocal range.

She previously tweeted: "U can tell when I write a singing song from beginning to end cuz I write in a comfortable key 4 my range. SAVE ME & FIRE BURNS (sic)."

And Nicki - whose real name is Onika Tanya Maraj - has admitted her 2012 songs 'Champions' and 'Freedom' are her favourite singles.

She said: "Yup "Champions". Love that song. Yikes. Nas, Drake & Jeezy. Very proud of my hook and harmonies on that one too! that beat. That vibe.

"Spent days writing Freedom. One of my career faves. Facts on top of facts on top of facts. The beat>>>> wrote Freedom in Malibu (sic)."
