Austin Mahone, Ariana Grande Set To Party At The VMA Pre-Show!

The rising pop stars will perform at the VMA pre-show, live at 8 p.m. ET/PT from Brooklyn

We already know who's performing at the 2013 MTV Video Music AwardsKaty, Kanye, Gaga and Miley (to name just a few) — but now, we know who will help kick things off during the pre-show.

Two of pop music's brightest young stars, Austin Mahone and Ariana Grande, have been confirmed as performers at the show before the show, but they're not the only ones joining the pre-show party: dynamic duo Nervo will be there too, serving as guest DJs on the red carpet!

Mahone, a VMA nominee in the Artist To Watch category, will serenade the streets of Brooklyn with his single "What about Love" from his debut album, due later this year. He'll also perform a special pop-up show on Saturday, August 24, as part of a week-long series of free VMA concerts happening throughout New York City and Brooklyn, and he'll co-host MTV's "10 on Top," which airs that same day at 12:30 p.m. ET/PT.

Grande will perform a pair of songs during the pre-show: "The Way" and "Baby I," from her upcoming album Yours Truly. She'll also co-host this week's episode of MTV's "10 on Top" on Saturday, August 17 at 12:30 p.m. ET/PT.

The 2013 VMA pre-show airs live on Sunday, August 25 at 8 p.m. ET/PT from outside the Barclays Center in Brooklyn, with MTV News' Sway Calloway, James Montgomery and Christina Garibaldi bringing you all of the action and interviews with the hottest names in music ... and it all leads up to the big show itself, the 2013 MTV Video Music Awards, live at 9 p.m. ET/PT!
