The 21-year-old rapper-turned-actor – now known by his real name, Shad Moss – just shot his first sex scene for HBO's Entourage.
"It's with a porn star," he told PEOPLE Wednesday night during the N.Y.C. premiere of the show's fifth season. "It was unreal because I didn't know that I had a sex scene until that day. When I saw a robe in my trailer, I thought, am I taking a bath?"
The actor admits that he shows some serious skin in the scene. So will Moss – who joins the cast as a struggling comedian – be completely nude?
He said coyly, "You have to watch it." –Susan Yara
