Every week, Scream Queen fans are haunted by the same question: Who's the killer? And in this exclusive video, the star-studded cast shares their theories.

"I think I could be the killer," admits Emma Roberts. And while we wouldn't be shocked if Chanel Oberlin was the deadly devil, Skyler Samuels has a different theory. "Truly, my money's on Hester," Samuels says.

But how would Lea Michele feel about this? "I would be honored to be the killer," the Glee alum says.

See what Ariana Grande, Nick Jonas, Keke Palmer and others have to say about who's under the devil mask in this video below:
