Christina Aguilera allegedly got into a heated argument with Mickey Mouse while going a trip to Disneyland for her birthday on Dec. 18, TMZ reports.

The verbal dispute allegedly erupted when the performer dressed as Mickey Mouse denied Aguilera's request for a photo because they were going on break.

Aguilera was apparently upset at the performer's rejection of her request and immediately began calling Mickey Mouse an "a**hole" and asked the performer "Do you know who I am?"

Aguilera's family and friends who also attended the birthday celebration joined in on the Disneyland meltdown and began "hurling threats" at the performer according to TMZ sources.

The argument allegedly became so heated that the Mickey mouse performer was "ushered to a safe zone" in a different part of Disneyland to avoid further dispute with the former "The Voice" judge.

Additional security was called to escort Aguilera off the premises but by the time authorities arrived, Aguilera and her team already left, says TMZ.

Despite the alleged dispute at Disneyland, Aguilera and her crew appeared happy and unbothered in an Instagram photo that Aguilera posted while celebrating her birthday at Disneyland, Us Weekly reports.

Two years ago in May, Christina Aguilera made headlines for another argument she had with her follow "The Voice" judge, Adam Levine, RadarOnline reported at the time.

Levine's decision to have his finalist, Tony Luca, sing Jay-Z's "99 Problems" allegedly offended Aguilera because the song was meant to be aimed at her, says RO.

One of the lyrics to "99 Problems" reads, "I've got 99 problems but a bitch ain't one." Though the song is a Jay-Z classic, Levine allegedly told Luca to sing it with the intention of dissing Aguilera, said an RO source.

Aguilera naturally took offense to the musical jab, confronted Levine during "The Voice" finale rehearsal, and demanded that NBC executives make Levine change the word "bitch" to "chick."

"Christina is so sick of Adam being looked at as the golden boy of the show," said an RO source at the time. "If America knew how disgusting he was, they would be appalled."
