Nick Jonas is promising "a departure" with his upcoming duet with pal Demi Lovato.

"It's more on the folk side of things," he told ETonline at the MTV Video Music Awards on Sunday. "It's really the song and our two voices and blending that together, hopefully at some point we'll release it."

Jonas played coy on a release strategy, only saying, "I think we're going to save it for later on." (The two run Safehouse Records together.)

He was a bit more forthcoming when asked about his new music video for "Levels," which features a bevy of bikini-clad beauties.

"It is really steamy!" he said. "It was actually literally really hot when we shot it. It was a fun shoot -- lots of beautiful women, cool art direction, it was a good time."

Jonas not only has a brand new single, but he'll kick off a new tour on Sept. 6 in Hershey, Pennsylvania, with special guest Bebe Rexha.

"What we're trying to do is create really original content for every song with some great projection that we're working with, which I think is going to be cool," he teased. "Anytime you can bring the music to life with a visual, I just think it makes it that more exciting. I'm just thrilled to get back out on the stage with the fans and have a good time."

Meanwhile, Lovato spoke with ET about her sexy new Confident album cover. See the interview in the video below.
