Eminem appears to be teasing a new song called 'Walk on Water'.
The 45-year-old rapper took to Instagram on Wednesday night (08.11.17) to share a doctor's note with the words written on it along with the advice of "take as needed".
The note also has the phone number "1-833-2GET-REV" and the website www.askaboutrevival.com printed on it.
Those who click on the URL are taken to a fake drug website, which is all about conditions which the factious drug REVIVAL can treat.
Along with a video the homepage reads: "Are you ready for REVIVAL?
REVIVAL is proven to effectively treat people with Atrox Rithimus. If you've tried other treatments without getting the AR symptom relief you need, REVIVAL could be music to your ears.
"Hikers in video not actual AR sufferers/hikers. (sic)"
'Walk on Water' looks to be the lead single from the 'Lose Yourself' hitmaker's forthcoming ninth studio LP, which just so happens to be titled 'RƎVIVAL'.
Eminem is yet to explain the link between the medicine and his new music.
The song will be the rapper's first new music since 2015's 'Kings Never Die', which featured Gwen Stefani.
All signs appear to be alluding to 'RƎVIVAL' being part of a trilogy, following 2010's 'Recovery' and 2009's 'Relapse'.
The single teaser comes after reports that the hip-hop icon - whose real name is Marshall Mathers - is in talks to perform at the MTV European Music Awards (EMAs) this Sunday (12.11.17) at London's The SSE Arena, Wembley.
A source said recently: "This is Eminem fully relaunching his career after a few years out and gathering his thoughts.
"It will be a massive performance."
