The 21-year-old is reported to have cut her show short at the Los Angeles holiday concert after experiencing some technical difficulties with the sound system.

The frustrated singer is alleged to have abruptly exited the stage but not before allegedly unleashing some colourful language on her way out, to an audience largely filled with young people.
