EXCLUSIVE: Nick Jonas Strips Down in This 'Kingdom' Sneak Peek and Prepares For the Fight of His Life!

Note to self: Don't mess with Nick Jonas!
The "Close" singer is stripping down and stepping back into the cage in this week's all-new episode of Kingdom, but don't let his sexy muscles and knockout bod distract you -- his punch is lethal.
Jonas, as his kickass MMA-fighting character, Nate Kulina, is gearing up for the fight of his life in Wednesday's episode "Halos" -- and only ET has your exclusive first look at the heart-pounding moment!
Nate is looking to end his painful losing streak for Navy Street and to prove to his father Alvey (Frank Grillo) and everyone else that he's still a viable fighter.
As he gears up for the big moment, Nate hears past echoes of self-doubt in his mind. "You're a great athlete, Nate," the voice says. "I don’t know if you're a great fighter. The difference between good and great -- it's a f**king hundred miles. It's a mindset."
Jonas previously opened up to ET about Nate's struggles outside of the ring as grapples with his sexual identity. "He's still trying to figure it out, and it'll be a journey for sure," the 23-year-old singer/actor said of portraying a gay character. "I'm willing to go wherever I need to go with the story and we'll figure it out when we get there, I guess."
Don't miss the results of Nate's fight when Kingdom airs Wednesday, July 6 at 9 p.m. PT on AT&T Audience Network.
