Michael Phelps
 

Michael Phelps said the 2016 Olympics would be special because it would be the only time he would compete in front of newborn son Boomer.

Well, this weekend, Boomer experienced another first. He got to see his dad lip sync Eminem's "Lose Yourself."

This is done incredibly well. Phelps kind of looks like Eminem with the hoodie, nails the mannerisms and knows the lyrics. He also manages to weasel his Under Armour branding into his costume (see the logo on top of his head).

Phelps -- or as he is now known, "Swim Shady" -- made the performance on Spike's "Lip Sync Battle," presented by LL Cool J and Chrissy Teigen. Gymnasts Aly Raisman and Simone Biles performed Sia's "Cheap Thrills" with actress Olivia Munn. Spike posted the highlight:

Forget the argument of would you rather be a star recording artist or a star athlete. Just do both.
