Christina Aguilera
Xtina is best known for her unforgettable voice. She's been in the limelight since she was a teenager, but sometimes, she acts like she hasn't matured at all. Aguilera once made an entire store close down for an entire day just so she could shop there, which is sadly normal for very famous celebs like her. Even worse, she also made the staff on the clock stay out of the store while she looked so that she wouldn't be "bothered" by the masses.
