Emily axed from the X Factor

X FACTOR finalist Emily Nakanda has left the show after being caught in a second shock video — beating up a teenage girl.

“She has chosen to withdraw herself from the competition with immediate effect,” said a show spokesperson.

Sharon Osbourne, Emily’s mentor on the show said: “I am deeply saddened by this whole situation.”

The happy slapping video — sent via mobile phone to kids near Emily’s home — shows the 15-year-old launching an attack in her school uniform.

In it she gets the blonde girl in a headlock, swings her round by the hair, punches and batters her and shoves her to the ground.
