Grey, who performs on a song entitled Tragic Endings, will be making her latest appearance with Eminem.
As a little-known songwriter, she wrote one of Eminem's number-one hits — 2010's Love the Way You Lie featuring Rihanna — and later appeared alongside Eminem on Dr Dre's track I Need a Doctor.
Eminem's new album only appears to include one other rapper and he picked one who is relatively obscure — Phresher, who has been making a buzz on the New York club scene. Phresher rejoiced on his Instagram account over the massive exposure he is likely to enjoy through the album.
On "Walk on Water," Eminem rapped at length about his fears of not living up to his own standards or fan expectations as he comes up with new material.
The 45-year-old rapper has been quiet over the past few years but has twice returned with angry denunciations of President Donald Trump, most recently with a freestyle rap aired at the Black Entertainment Television Hip-Hop Awards.
