"Okay, okay I get it!" the Jack Ryan star responds. "No, no, no, she's right, you better be funny," MGK chimes in with a hard stare.
In the second clip, Gardner asks the MC-turned-pop-punker (born Richard Colson Baker) how he came up with his stage name. "Oh, my mother's maiden name is Machine Gun," he jokes.
MGK recently released the 50-minute Downfalls High -- the companion movie to his Billboard 200 No. 1 album Tickets to My Downfall -- which he wrote and directed with Mod Sun and which features frequent collaborator Travis Barker, Sydney Sweeney, Chase Hudson, Trippie Redd, Blackbear, Iann Dior and Maggie Lindemann.
