Who Are The Mysterious Members Of Joe Jonas' New Band DNCE?

Get to know the 'Cake'-eaters.

Last night, Joe Jonas' funky new band DNCE lived up to its name and premiered a highly danceable new song called "Cake By The Ocean." Joe and co. were appropriately stoked, posting a celebratory video to Instagram shortly after.

Based on this video and the band's official Insta page, it's clear: This isn't just a Joe-centric project. There are three other members in DNCE that help the springy, buoyant funk-pop come to life -- and as we've mentioned before, their names are JinJoo Lee, Cole Whittle and Jack Lawless. But who are they, really? And how did JJ get hooked up with them to form, as their Insta page puts it, "your new favorite band"?

That's what we're here to find out.
