X-Factor Season 3 winner Leona Lewis was attacked by an unidentied young man at a book signing meet and greet session for her new book “Dreams” at Waterstone’s booksellers in Piccadilly earlier today (Oct 14)! Her publicist, Stuart Bell, released a statement shortly after confirming the incident:

“Leona was the victim of an unprovoked attack. The police were called immediately and medical attention has been sought. Leona is understandably shaken and apologizes to the fans she was unable to meet and complete signings.”

Lewis was posing for pictures and signing autographs Wednesday when a 29-year-old man came up and hit her. Security immediately reacted, escorted Leona to safety and arrested the jerk on the spot.

She was taken to see a doctor just to be on the safe side and can be seen in the picture above (L) leaving the signing in a shocked/shaken state. London’s Metropolitan police say the man was arrested on suspicion of assault and is currently being held in their custody.
