Olivia Munn Enlists Simone Biles and Aly Raisman to Surprise Michael Phelps on Epic Lip Sync Battle: All-Stars Live
Team USA took over Sunday's Lip Sync Battle.
During a special live edition of the hit series, fans eagerly awaited Michael Phelps' performance – but little did they know, they would be lucky enough to watch a few more famous Olympians battle it out.
When Olivia Munn took to the stage to perform "Cheap Thrills" by Sia, the actress decided to bring out gymnasts Aly Raisman and Simone Biles.
The audience was blown away by the surprise, including co-host Chrissy Teigen, who cheered as Raisman, 22, and Biles, 19 – both clad in tutus – danced and twirled around Munn, 36.

"When I found out that Michael Phelps was joining our set, I said, 'The only way to beat a gold medal champion is to bring two gold medal champions,' " Munn later told host LL Cool J.
"That was awesome," admitted Phelps, 31. "I loved being on the team with these girls and seeing them perform is so special."
But ultimately, no one could compete with Phelps' epic rendition of Eminem's "Lose Yourself" – which earned the star swimmer the winning title of the evening.
Lip Sync Battle returns Oct. 12 at 9 p.m. ET on Spike TV.
