Ariana Grande's duet with Nathan Sykes of the Wanted had finally hit the Internet in full, and it was worth the wait. The two of them have some seriously powerful pipes!

The song is perfect for fall, featuring tinkling pianos and heartfelt vocals. Alternately and then together, Grande and Sykes belt, "Almost, almost is never enough / So close to being in love / If I would have known that you wanted me / The way I wanted you / Then maybe we wouldn’t be two worlds apart / But right here in each others arms."

Like most of Grande's songs, this one is evocative of early Mariah Carey -- and it's a timely leak, as well, as Grande and her longtime boyfriend Jai Brooks just split.

The song is from Grande's long-awaited debut, 'Yours Truly,' due Sept. 8. (You can check out the track listing here!)

Grande and Sykes recently performed 'Almost Is Never Enough' together live, and they had so much chemistry together that we almost want him to take Brooks' place in her heart ... unless Justin Bieber does that first!
