On Spike TV’s Lip Sync Battle’s first ever “LSB All-Stars: LIVE” show, Olympic gold medal magnet Michael Phelps gave it his all during a performance of Eminem’s “Lose Yourself.” Wearing jeans and a hoodie, Phelps channeled his inner B. Rabbit and delivered the 8 Mile smash hit like he’d done it a million times before. It got Slim Shady’s attention, as well, prompting the Detroit Hip Hop legend to post the YouTube video to his Twitter account.
