'American Idol' is airing episodes now that show who's going to Hollywood, and among everyone else auditioning the 15-year-olds trying out are completely holding their own.
Georgia teen Lauren Alaina, 15, blew the judges away with her amazing voice and she's already getting tons of buzz about being Idol's 10th (and youngest) winner.
Also a judges' fave was 15-year-old Louisiana native Jacee Badeaux, who sang "Sittin' on the Dock of the Bay" and scored three yes's. Watch out for this one, Biebs.
The youngest hopefuls are having so much success, in fact, that Ryan Seacrest noted every 15 year old who the judges saw in Milwaukee received a golden ticket taking them to the next round.
