Posted by Sabrina B. @gametimegirl Before the main event action between The Rock & John Cena began last night, thousands of fans in attendance at Sun Life stadium in Miami were treated to some performances from Hip Hop’s own Machine Gun Kelly, who was introduced by his boss Diddy, and Miami’s own Flo Rida.
