If you weren't planning on watching the MTV Video Music Awards pre-show—or had no idea such a pre-show existed—we've got two names that might make you alter those plans: Austin Mahone and Ariana Grande.

Neither can legally drink and the former can't legally vote, but these two pop powerhouses know how to please a crowd. Mahone has built a legion of devoted "Mahomies" since he started posting YouTube videos, and hits like "What About Love" have earned him a coveted "Artist to Watch" VMA nomination this year. 20-year-old Grande was in very real contention for "song of the summer" this year with "The Way" featuring Mac Miller. Her upcoming album Yours Trulyis one of the most highly-anticipated debuts of the year.
