Leona Lewis has spoken for the first time about being attacked by a fan during a book signing two weeks ago. She was punched in the face by the man, who was later sectioned under Mental Health Act. Leona 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." She added that although she doesn't have a minder with her at all times, she does have people who look out for her. Leona also spoke about this year's crop of X Factor contestants: check out the interview below.
