Eminem warns Michael Phelps, ‘wait until you see me swim’

Eminem must be practicing his swimming skills by now after US Olympian Michael Phelps spoofed his signature moves and attire as the competitive swimmer lip-synced his 2002 hit “Lose Yourself” on Spike.

Phelps won the Sunday episode of “Lip Sync Battle: All Stars Live” against fellow Olympians Simone Biles and Alexandra Raisman after recreating Eminem’s music video of “Lose Yourself.” Touted as the most decorated Olympian of all time, Phelps admitted that Eminem’s “Lose Yourself” is included in his pre-race playlist.

Reacting to Phelps’ performance, Eminem said it succinctly, “but wait until you see me swim.”

It is not exactly clear if an actual rap battle or a swimming race is forthcoming between Slim Shady and the the 31-year-old newly retired swimmer. But what is certain is that Phelps joins US President Barack Obama and other Eminem fans across the globe. (Read: Eminem’s ‘Lose Yourself’ preps Obama for DNC speech)

Eminem new album 2016

While Slim Shady was quick to react to Phelps’ spoof Sunday night, the multi-awarded rapper remained mum on the highly anticipated Eminem new album 2016. He last released an album in 2013 with “The Marshall Mathers LP 2.”

Eminem was last seen in public during Drake’s tour stop in Detroit, Michigan. The two rappers performed their 2009 collaboration “Forever” and ended speculations over a supposed conflict. (Read: Watch Eminem, Drake share stage in Detroit, end speculations over a brewing rap battle)
