Superstar TV presenter and bestselling author Alesha Dixon gives you a backstage pass to hang out with the world's number one pop star in her brand-new book -- a fresh, funny spin on Freaky Friday! Naomi is the biggest pop star on the planet at the age of thirteen ... but she's also tired of the constant touring, bored with having the shopping center closed for her to wander alone at midnight, miserable at not having any friends. Ruby is Naomi's biggest fan. She knows the words to every song, she can replicate every dance move, she dreams of being as confident as Naomi, and to stop being "invisible" to her family, to her classmates ... to everyone, really. When the girls have an unexpected encounter and swap bodies, Ruby is launched into the limelight. Will she adore her new A-list life, or will she end up as lonely as Naomi? And will Naomi discover she can be a huge celebrity AND a normal girl after all?
