Christina Aguilera may have ruffled some feathers at the world’s happiest place.

The pop star celebrated her 34th birthday at Disney's California Adventure a few weeks back with her crew, but it wasn’t all blissful.

According to TMZ, the group wanted to take a picture with Mickey Mouse, but since it was his break time, Aguilera was told to wait.

Aguilera lost it, and called Mickey an "a**hole." We're told she even dropped the dreaded, "Do you know who I am?"

Xtina's crew started hurling threats, we're told … and Mickey had to be ushered to a safe zone — out of public view. Security was called, but by the time they arrived … the former Mouseketeer had already split.

Sounds like Xtina had some birthday juice!

We're guessing Mickey didn’t spoil the fun completely — She wrote on Instagram, "Fun birthday celebration at the happiest place on earth #disneyland."
