While we don’t know too much about John Stamos’s Scream Queens Season 2 character, one’s thing certain: He’s sexy with a capital S.

On Wednesday, the actor and former Full House star took to Instagram to offer a behind-the-scenes peek at what goes on while the cameras roll while also teasingly sharing a glimpse of himself almost in the nude. “Dirty day on the set of @screamqueensfox #showertime,” he wrote as the caption to his moody shot.

The image captures Stamos from the back as he faces three spooky, dark showers and holds open a robe that covers his derriere and showcases his muscular back.

So why exactly is Stamos removing the robe? We have yet to find out, but what we do know is that the actor portrays Dr. Brock Holt, a “secretive” head surgeon inside of the hospital that serves as the centerpiece for the second season's shenanigans.

Here’s hoping exciting plotlines—and a better glimpse of Stamos’s physique—are revealed once Season 2 premieres Tuesday, Sept. 20, on Fox.
