Selena Gomez Jingle Ball Video may have put the former Disney star on the naughty list. It seems Selena was having problems with her microphone while she was singing at Jingle Ball in Los Angeles on Dec. 6. Gomez was caught lip-syncing and then caught cursing.

The annual KIIS FM Jingle Ball in Los Angeles was not an early Christmas gift for Selena Gomez. But it was an unexpected present to the 20,000 fans who showed up.

Selena Gomez was probably only lip-syncing during the dance parts of her performance at Jingle Ball, but being caught is no fun at all. Ask Britney's sister. Selena started having audio problems towards the end of the Jingle Ball set. Gomez pulled out her in-ear monitors and tried to continue the performance.

Selena couldn't make out her voice over the stage monitors and dropped the F-bomb at Jingle Ball after getting "visibly angry to verbally angry," according to an eyewitness. Gomez's microphone went live and he was heard yelling, "What the f**k?"

Why the mic would go on at all if Selena was lip-syncing, I don't know. But Gomez walked off stage. The "Trust in me" singer apologized for the sound problems and continued the show. Gomez finished "Come & Get It" ran off and stage and well that was it. Merry F-Bomb Christmas.

Selena Gomez fans immediately too to Twitter to either say they understand, or to deride her for lip-syncing.
