Jessica Sanchez may have lost the American Idol crown to Phillip Phillips last season, but she won BIG at the Democratic National Convention on Wednesday night!
Her soulful cover of Marvin Gaye's You're All I Need to Get By (above) brought the entire audience to their feet as everyone grooved along with the young singer and the God's Appointed People Choir, all of whom did an amazing job backing Sanchez's incredible vocals up!
Isn't it crazy that voice is only 17 years old!? It's SO powerful and is DEFINITELY going places in the music industry!
