For her forthcoming album Unbroken (out September 20), Demi Lovato has been hooking up with the best of the best. Yesterday, we brought you "All Night Long," her SMOKIN' hot collabo with Missy Elliott and Timbaland. Today Demi continues down her path of incredible-ness with her most recent tune "Who's That Boy," featuring electro-pop princess Dev.

As is the case with "All Night Long," Demi is full-blown pop on "Who's That Boy," and even showcases a little bit of her R&B side. In simpler terms, she sounds like a bad-ass chick who's gonna get whatever she wants, no matter what. And what she wants is to know who the HELL that random hot guy is in the corner: "Don't know who you are/But you look like a star/And everybody here be thinking/Who's that boy?/Wanna take you home/And get you all alone/Everybody here is thinking who's that boy?" Dev's also pretty curious as to the identity of this unknown hottie, but takes a more ballsy approach at reeling him in: "Gimme the green light/Kiss my lips/Who's that boy watching my hips?/I, I wanna know who you are/My name is Dev/And you can be my star."

We've said this before and we'll say it again: WHAT IS WRONG WITH DUDES?! What kind of insane bro wouldn't want to reveal his full name to Demi Lovato or Dev? Or like, at least his Twitter handle?!
