“Hey man. I’m your worst nightmare,” a be-wigged Jeffrey Ross whispers to Justin Bieber in the new promotion for his upcoming roast on Comedy Central. “Are you ready?” “No,” Justin whimpers. Ross leans in and says, “I want to stick my pinky in your a–hole.” HA! It’s funny because WE’RE ALL THINKING IT! Right? Right? At any rate, this roast is shaping up to be QUITE a shit-show, what with Justin pleading with Seth Rogen to lampoon him and ubiquitous wee comedian Kevin Hart as the emcee – YIKES. Watch the commercial below.
