The room erupts in cheers and tears as Miley takes the stage for a surprise performance of her hit "The Best of Both Worlds." Then, the girls go wild when Billy Ray takes the stage to say hi to his daughter's biggest fans.
One girl even fell to the floor, crying happy tears! "I watch her shows all the time and I watch them On Demand and I love her songs and everything and it's wonderful," she says.
The fun continues with an exclusive tour of American Girl's headquarters.
