Eminem, Royce Da 5’9″ and Mr. Porter Rip It in BBC Studios

Eminem, Royce da 5'9" and Mr. Porter hit up Tim Westwood's spot during a promo stop in London and the trio rip it, freestyling in the BBC studios. With Alchemist on the ones and twos, Mr. Porter sets things off, followed by Royce, who shouts out Slaughterhouse before making room for Em. Eminem goes in, starting off with some celebrity name-checking (Kim Kardashian, Nick Hogan) before threatening to cut someone's testicles off and sexually assaulting the elephant man.
