The young divas make quite the dynamic duo on this collab about crushing hard. Newly pregnant pop star Dev, 22, rap and sings her way through her featured verse, while Disney darling-turned-comeback kid of the year Lovato,19, lays her strong R&B-leaning vocals over the mid-tempo beat.
"Now I don't know who you are/ But you look like a star/ And everybody here be thinkin'/ Who's that boy?/ Wanna take you home/ And get you all alone/ And everybody here is thinkin'/ Who's that boy?"
The Demi-Dev duet is Lovato's second superstar collaboration to drop this week. On Wednesday (Sept. 14) Demi momentarily unleashed her Missy Elliott and Timbaland-assisted 'All Night Long,' teasing out the track with a limited time-only stream on her official website.
Both tracks give us a nice, light-hearted departure from the emotional power ballad lead single, 'Skyscraper,' as Demi promised in an interview with AOL Music.
