Joe Jonas wants to make 'Camp Rock 3', but only if it's "R-rated"

Asked if he would agree to making 'Camp Rock 3', the DNCE frontman said: "If it made sense, sure. For all of us -- Demi, Nick, it would be funny to do a spin on it. Do the graduating days, make it kinda dark. An adult film. Well, not an adult film. An R-rated film. We've joked around about the idea a couple times."

And if the 'Cake By The Ocean' hitmaker does to take part in a racier version of the franchise - which was first made popular with 'Camp Rock' in 2008 - he's already well versed in stripping his kit off after recently starring in an underwear campaign for Guess.

Speaking about the shoot, Joe said: "You're trying to flex as much as you can, because you want to look your best. There was a lot of laughing going on. When you're shooting, you're so exposed in your underwear--but after a time you forget, so you're walking around catering in your underwear."

Despite having been seen without a shirt by millions of people, the former Jonas Brothers star wouldn't consider himself a "sex symbol".

He told Marie Claire magazine: "There's a little bit of an idea that you've gotta stay in the gym if you're going to be in an underwear campaign, so you have that in the back of your head. But it's a lifestyle now. It was life-changing, I had to focus on getting in great shape for this. But no, I don't think I'd consider myself a sex symbol."
