Christina Aguilera did the unthinkable during a recent birthday outing to Disneyland by calling Mickey Mouse an A**hole.

According to TMZ, the former Mouseketeer had quite the meltdown Dec. 18 at the famed Anaheim, California park with her fiancé Matt Rutler and a group of friends.

The 34-year-old diva apparently lost it when she wanted to take a pic with Mickey Mouse and found that the character was on a break.

A source told TMZ that Aguilera called Mickey an “a–hole” and demanded, “Do you know who I am?” TMZ claims that the poor Disney character had to be taken to a “safe zone” when members of Aguilera’s party began “hurling threats.”

Another source close to The Voice coach told Us Weekly that “Christina is a frequent guest at Disneyland. She loves the park and they adore her.”
