Machine Gun Kelly "Invincible" f/ Skylar Grey LIVE @ Wrestlemania [Video]

Last night at Wrestlemania, Machine Gun Kelly received a big, primetime look as he performed "Invincible" alongside Skylar Grey and an intro from his Bad Boy boss Diddy himself. The performance was the intro for John Cena prior to the 'Once In A Lifetime' main event between Cena and The Rock. As such, the performance became even more entertaining because MGK received the boo birds for his spoken word outro backing Cena in front of a pro-Rock crowd in Rock's hometown of Miami. Hah! Pretty awesome. Watch and see the performance in its entirety above.
