Lily Allen left in tears at O2 gig?

Lily Allen was left in tears after violence broke out during her gig at the O2 last night, reports claim.

The 24-year-old singer, who today clarified her departure from music, turned away and left the stage as two middle-aged men came to blows in the crowd, reports The Sun.

Upon returning to face the audience, she said: "That's the worst sort of violence. It's f**king sick and you lot should be ashamed of yourself."

Allen, who now plans a career in fashion as well as an appearance on Come Dine With Me, wryly dedicated a song to Tory leader David Cameron coming in the wake of his comments about the star.
