'X Factor' champ Leona Lewis 'slapped' at London book signing

Leona Lewis was at Waterstones book store in London earlier today, signing copies of her autobiography, “Dreams”, when she was assaulted by a man.
The man allegedly slapped the singer, and was subsequently arrested.
A Scotland Yard spokesman said, “The female did not require hospital treatment – we are at the scene.”
That’s just awful, I hope she gets some better security for any future outings. Shame on that guy for hitting a lady.
