Nick Jonas is currently romancing Priyanka Chopra, and it's not hard to see why she fell for him. Not only can the 25-year-old definitely sing, but he can also act and play the guitar. Oh, and in case you haven't noticed yet, he's pretty damn easy on the eyes, too. Yep, Nick can rock just about anything: a t-shirt, a tux, or a sexy muscle tank, but honestly, we prefer him shirtless. I mean, have you seen those abs and biceps? It should be a crime for Nick not to show them off. After all, he does work hard for them.
