Christina Aguilera is reported to have hurled abuse at a Disney California Adventure theme park employee dressed as Mickey Mouse during a trip last week.

Christina Aguilera reportedly called Mickey Mouse an "a**hole".

The 34-year-old star celebrated her birthday at Disney's California Adventure theme park last week and is said to have got into a heated argument with the popular cartoon character.

The 'Genie In A Bottle' hitmaker wanted to have her and her friends' picture taken with Mickey but as he was due a break she was told she would have to wait until he came back, which is when she flew into a rage, gossip site TMZ.com reports.

Christina is said to have called the man dressed in a Mickey Mouse costume an "a**hole" before questioning whether he knew she was famous by saying, "Do you know who I am?"

The blonde beauty's crew is also reported to have begun hurling abuse at the amusement park's employee, resulting in him being taken to a safe zone and the police being phoned.

However, it's claimed that by the time law enforcement arrived, Christina - who, along with actor Ryan Gosling and former pop star couple Justin Timberlake and Britney Spears, was a member of The Mickey Mouse Club as a child - and her pals had already left.

The 'Beautiful' singer failed to recall the incident when posting an image of her and her friends on Instagram, however.

Alongside the snap she wrote: "Fun birthday celebration at the happiest place on earth #disneyland (sic)."
