A man has been arrested after allegedly assaulting Leona Lewis during a book signing in London.
The 24-year-old X Factor star received medical treatment for a cut and bruising to the side of her head after the incident.
Leona was "badly shaken", but thanked fans for their messages and kind words her spokesperson said.
She had been signing copies of her autobiography, Dreams, when the alleged attack took place.
"He walked up there with the book, she signed it and, as she looked up, he just punched her," an eyewitness revealed.
The man is also said to have screamed "I love you, Leona".
Leona - whose new album Echo is due to hit the shelves in November - "apologises to the fans she was unable to meet and complete signings for", her rep has added.
