Sharing a picture of the two in the recording studio on Instagram, the 26-year-old English singer revealed he is featured on the track River, with Eminem's latest album reportedly leaking a day early, according to Capital Xtra.
The dog tags are engraved with Shady, while the steel-prints have the lyrics to Eminem's new track, "Walk on Water", with the "Love the Way You Lie" rapper's own handwriting. Each track was penned by multiple writers, but Slim Shady is credited in the entire tracklist, save for "Remind Me (Intro)".
Speaking about the collab recently to The Times, Ed said the change to work with the 8 Mile star was the "Highlight of my career" but offered no more details about the project.
The song talks about white privilege, racism, and violence against African Americans. The Marshall Mathers LP, released in 2000, and the The Eminem Show, released in 2002, both went diamond, selling over 10 million copies each.
In celebration of the album's release, Eminem is hosting a pop-up shop in his hometown, Detroit, on December 15 and December 16, with the main meal served at the event a homage to what are perhaps Eminem's most famous lyrics: mom's spaghetti. What's yours? Sound off in the comment section.
