Eminem has new music on the way. After announcing Revival in a mysterious drug ad, Slim Shady teases its first single, “Walk on Water.”

Marshall Mathers posted a prescription note, continuing the drug ad’s theme. It features the title “Walk on Water” and says: “Take as needed.”

It’s unclear when the song will drop, but it could be this week, which would coincide with 8 Mile’s 15th anniversary. To celebrate the film’s success, Slim has announced a special Detroit screening.

Last month, Em’s mysterious drug ad popped up during “Saturday Night Live.” Further fueling album rumors, Shady was named “SNL’s” musical guest on Nov. 18. Revival is expected to arrive on Nov. 17.

Additionally, Marshall is rumored to perform and debut new music at the MTV EMA 2017 at London’s SSE Arena, Wembley on Sunday (Nov. 12).

Despite the teasers and hints, Em has yet to officially announce Revival, his first album since 2013’s The Marshall Mathers LP 2.
