Get ready to rock out with Barbie™ in her latest family adventure, Barbie™ in Rock -N Royals.

Sing and dance along with Barbie as she finds out what it's like to be a rockstar in Barbie™ in Rock -N Royals.

Two very different worlds collide when a mix-up sends Princess Courtney to Camp Pop and Erika, to Camp Royalty. While the leaders of the rival camps try to correct the mix-up, Courtney and Erika learn to adjust to exciting new worlds and have fun, making some unexpected friendships along the way.
