Leona Lewis has spoken for the first time about being attacked at a bookshop earlier this month - and revealed “it could have been worse”.

The former X Factor winner was punched in the face as she signed copies of her autobiography Dreams in London.

Peter Kopwalczyk, 29, has been charged with assault over the incident and sectioned under the mental health act.

In an interview with Sky News, Lewis said: "It could have been worse. I'm still alive, it's just something you have to deal with when you have fame and the positives far outweigh the negatives.

"I don't like to dwell on the negatives, I'm a very positive person."

Leona Lewis talks about bookship attack on Sky News.

Despite the attack, the singer said she had no plans to change the way she lived her life or her approach to personal security.

Kopwalczyk, who is thought to be a former X Factor reject, was deemed unfit to appear in court earlier this week.

As well as promoting her autobiography, Lewis is currently preparing to release her second album, Echo.
