Watch Ariana Grande and The Wanted's Nathan Sykes perform "Almost Is Never Enough" live!

To be honest, we're sort of shocked that the internet is still breathing right now. Why? Well, on the Atlanta stop of her opening act gig on Justin Bieber's "Believe" tour, Ariana Grande brought out The Wanted's Nathan Sykes for a live debut of their duet, "Almost Is Never Enough." (That's a lot of pop star name-drops in one sentence, don't you think?) Then again, if the interweb is still alive post-Ariana Grande and Justin Bieber kiss-gate 2013, then we're pretty sure her constitution can withstand anything!! (The internet is a lady, right?)

Watch Ariana Grande and The Wanted's Nathan Sykes perform "Almost Is Never Enough" after the jump.

Unlike Ariana's other '90s throwback jams like "The Way," "Baby I," and the Big Sean-assisted "Right There," "Almost Is Never Enough" -- which will appear on Ariana's forthcoming Yours Truly (Sept. 3) -- is a soft, sparse ballad, leaving ample room for both vocalists to shine. And by "shine," we literally mean WAIL.

In the below video, Ariana opens the track, then welcomes Nathan to the stage where the two proceed to serenade each other like pros (amidst crazy, shrieking screams from the crowd). And sure, while we've yet to hear the full studio version, we feel pretty confident in our assessment that the record will sound like an updated version of Mariah Carey and Boyz II Men's "One Sweet Day." Which obviously makes it that much better.
