Sunday night’s Lip Sync Battle: All-Stars Live featured an Olympic-style showdown.

In a surprise appearance, “Final Five” members Aly Raisman and Simone Biles helped out actress Olivia Munn during her match-up against a lineup of stars, including fellow Olympian Michael Phelps. Raisman, who recently became BFFs with Munn and her beau Aaron Rodgers, showed off her dance moves during a performance of Sia’s “Cheap Thrills.”

Although Raisman and Biles did their best to try and beat Phelps, his amazing rendition of Eminem’s “Lose Yourself” ended up being another gold medal worthy performance. Not even music superstar John Legend, who teamed up with Stevie Wonder on Outkast’s “Hey Ya,” or Terry Crews’s election year inspired jam could top the world’s most decorated Olympian.

It was a pretty spot on performance, so Phelps definitely deserved being crowned champ.

Hopefully Raisman will get another shot at Phelps in a future episode, as there may be a Lip Sync Battle rivalry brewing between the high-profile Team USA stars. The Needham native tweeted out a tongue in cheek post over the results accompanied by an awesome photo from the live special.
