We've already told you that Jonas' portrayal of Boone is straight-up comedic gold, but now it's time to learn a little bit more about the douchey – and potentially deadly! – new character.

"Boone is very intense," the "Levels" singer explained of his preppy role on Scream Queens. "He's got a lot under the surface that you don't see at first, and it all unravels as the show goes on."

Underneath Boone's perfectly color-coordinated surface, fans will quickly discover that the college student is harboring a crush for Chad Radwell, his big brother in the university's golf fraternity.

"I’ve been so honored to play some really strong gay characters," Jonas shared of taking on his second gay role in the past year.

"For Boone, in particular, and this show as a whole, everything is not as it seems," he teased. "So I would say get ready to be surprised by a lot of different things. In his heart of hearts, that may be who he is, but we’ll have to find out as we watch."

On Jonas' other hit series, Kingdom, the star plays fighter Nate Kulina, who specializes in wrestling and grappling, but the real fight is within himself. The season one finale revealed that Nate might be gay when he drunkenly found solace in another man's embrace after being turned away from a gay bar.

Jonas revealed that Nate's journey to self-acceptance will continue to "evolve" in the second season, and he's proud to be able to portray this story.

"I think it’s all about being true to who you are," Jonas said when asked what message he hopes to spread to his LGBT fans. He later added, "Whatever I can do for the community is just a blessing for me."

Fans will also discover at the end of tonight's premiere that there is a HUGE twist involving Jonas' character, and it will change everything you think you know about the Kappa Killer. "You'll have to watch to see, but basically you can expect the unexpected with my character," Jonas spilled. "I do kind of come in and out [of the series] which I think it a little fun element to the role."

"The idea is to keep the audience totally captivated and never knowing where it's going to go and I think that they've done a brilliant job doing that," he added.

And, of course, we HAD to ask Jonas the question that is on everyone's minds: Are you more shirtless on Scream Queens or Kingdom?

"I think it might be Scream Queens," the singer smiled. "There’s a scene or two that I’m shirtless in, but in Kingdom I play a fighter too, so there is a lot. It’s a lot, it’s a lot of shirtlessness."

Basically, set your DVRs because it's the fall of shirtless Nick Jonas -- and we wouldn't have it any other way!
