During an autograph session for Leona Lewis’ new book “Dreams,” Lewis was inexplicably duffed out by a fan. Lewis was then rushed to a nearby hospital and cancelled her performance which was to proceed after the signing.

According to reports…
The thug – said to be in his late 20s or early 30s – queued up for a signed copy of the singer’s new book, Dreams, and then…… attacked her in front of 200 stunned onlookers. Pretty Leona reeled back in shock clutching her face as her five burly bouncers dived on the attacker while cops rushed to the scene.

She was then rushed out of a side door by minders and taken to a top Harley Street clinic for emergency treatment. A pal of the star said: “Leona was utterly shocked and appalled as it came out of nowhere. “The man queued up patiently, then as soon as she signed his book he smashed her in the face.
