Machine Gun Kelly, fresh off the release of his latest album Bloom, joined UFC heavyweight champion Stipe Miocic courtside last night during Game 4 of the Eastern Conference Finals between Cleveland and Boston to pump up Cavaliers fans at Quicken Loans Arena in Cleveland. When his name is mentioned, the rapper gets a loud standing ovation from his hometown faithful.

MGK, whose mainstream popularity is rising after the success of his Camila Cabello collaboration "Bad Things," also performed during halftime. Miocic, who successfully defended his title on May 13, displayed his championship belts and even loaned one to the emcee. 

Bloom continues to do well with the public too, staying in the Top 10 in overall album sales.
