Michael Phelps has proven that he is indeed a champ! This time, on "Lip Sync Battle".

Sunday night's episode of "Lip Sync Battle" proved that Michael Phelps is not just about swimming. The Olympian champion added one more gold medal in his record-breaking collection of 23, in Spike's first ever "All-Stars Live Championship".

Donning a black hoodie and matched with his famous mean-mug, Phelps takes on the stage with Eminem's hit song "Lose Yourself".

And fans did lose themselves. In fact, many took to Twitter and expressed their admiration with Phelp's winning performance.

Phelps competed with other contestants including Terry Crews, who shared the stage with presidential impersonators for their take on "Fight the Power". John Legend also bought a Stevie Wonder impersonator for their rendition of Outkast’s “Hey Ya.” Actress Olivia Munn, who tagged along Olympic gymnastic stars Aly Raisman and Simone Biles performed Sia’s “Cheap Thrills.”

Despite performing solo, Phelp’s raw talent proved to be superior as he ended up as “Lip Sync Battle” champion.

Although it remains unclear whether Phelps will compete in the 2020 Olympics or not, perhaps it’s safe to say that he might have a shot on winning the Grammys or VMAs instead.

“Lip Sync Battle” Season 3 is set to premiere Oct. 12 at 9 p.m.
