Returning "The Voice Season 8" host Christina Aguilera spent her 34th birthday on Dec. 18 in Disney, where she got into a heated argument with Mickey Mouse, TMZ reported.
A theme park source told the publication that Aguilera and her crew tried to take a picture with Mickey Mouse at Disney's California Adventure. However, Mickey Mouse was on break so Aguilera was told she had to wait.
While she is in "The Happiest Place On Earth," Aguilera was not pleased at all. Infuriated, she called Mickey Mouse an "a--hole." Moreover, she reportedly asked the Disney character, "Do you know who I am?"
To make matters worse, Aguilera's crew reportedly gave threats so Mickey Mouse had to be kept in a safe zone. By the time security arrived, Aguilera and her crew had already split.
Aguilera's rep has yet to issue a comment.
Meanwhile, Aguilera is set to return as a coach on the NBC reality talent show "The Voice Season 8," which will premiere on Feb. 23, 2015. She left the show for the sixth and seventh seasons and was replaced by Shakira and Gwen Stefani respectively.
Carson Daly will also return as a host along with "Neon Light" singer Blake Shelton, "Animals" hit maker Adam Levine and "Happy" hit maker Pharrell William as coaches.
Other artists who appeared as judges on "The Voice" are Usher and CeeLo Green. The previous winners are Javier Colon, Jermaine Paul, Cassadee Pope, Danielle Bradbery, Tessane Chin, Josh Kaufman and Craig Wayne Boyd.
