Output:
Do not mess with Christina Aguilera, even if you're Mickey Mouse. The singer was celebrating her 34th birthday at Disney's California Adventure recently, but when she and her friends tried to take a picture with Mickey, they were told he was taking a break and they'd have to wait. (The visit took place on Dec. 18, according to Aguilera's Twitter feed.) A theme park source tells TMZ Aguilera flipped out, and in addition to throwing the predictable "Do you know who I am?" line, she also reportedly called Mickey an "asshole." Her friends started threatening him, the source says, and security was called. Aguilera—a former Mouseketeer, in case you'd forgotten—was already gone when they arrived.
