The much awaited event Jingle Ball 2013 has a lot of drama happening on its stage. Besides, Miley Cyrus twerking and grinding on Santa Claus, there is someone else, too, from the tinsel town making news on a performance at the concert. "Come & Get It" singer star Selena Gomez was caught in faux pas on the stage of the show being attended by thousands in Los Angeles on Dec. 6, 2013. The starlet attracted attention of gluttonous media and paparazzi as she was caught in the act of lip-syncing and using the F-word while on stage.

Contrary to her calm and sweet disposition on stage, Selena Gomez was seen in an avatar that former Disney star's fans may have not seen her in, prior to this act. During KIIS FM Jingle Ball happening in Los Angeles, Selena Gomez was seen cursing, lip-syncing and then storming off the stage.

The starlet was delivering her set at the Jingle Ball concert on Friday when she faced some technical glitches that hindered her performance which was being attended by thousands of her fans. The 21 years old actress had adorned a gothic avatar in a red strapless bodysuit layered with black embellished net gown. She had her lips done up with black lip color and wore a bob wig.

The songstress had finished performing her first song when she seemed troubled by some technical problems onstage. Following this she shocked the audience, as she was heard yelling the F-word. "What the F***?" remarked Selena Gomez onstage. It seems she was oblivious to the fact that her microphone was live.

"Sorry the sound isn't working!" Selena Gomez told her audience after the embarrassing onstage blowup. And she then walked off stage.

"Are you guys having a good night? I promise, a lot cooler people are gonna come out tonight," she told the crowd after returning, few moments later. It is reported that she had promised her fans two more songs, but she ended her performance with just one more hit of hers.

According to Hollywoodlife.com, "Come & Get It" singer Selena Gomez lost her cool because it was revealed that the starlet was mere lip-syncing during her performance. This happened due to the technical issues that cut the song in the midst of her performance bringing out the truth.

An eyewitness described her "visibly angry" while speaking about it to Hollywoodlife.com.

"She for sure said 'what the f--k," another eyewitness revealed to E! News.
