Did Christina Aguilera abuse Mickey Mouse?

Singer Christina Aguilera is said to have branded a Mickey Mouse an "as****e" after the mascot declined to pose for a picture as he was about to go on his break.

Aguilera was celebrating her 34th birthday at Disney's California Adventure with her fiance Matt Rutler and her friends, reports tmz.com.

According to a source, the singer even said, "Do you know who I am?" before the security was reportedly called on the scene but the star had left by the time they arrived.

The representative of Aguilera did not comment.
