I recently saw a music video that begins with a girl alone in her room. She turns her music (the song) up loud, eats a chocolate bar, and sings into her hairbrush like a microphone. At one point her mom walks in and interrupts her.
As the video progresses, her hair and makeup and outfit all get done and by the end she looks like a popstar.
I have no idea who sings this song and it's driving me nuts. Any help would be greatly appreciated!!
