Leona Lewis Punched In The Head By Fan

At a book signing yesterday, a fan came up to Leona Lewis to get his book signed. Once signed, he swung on Leona & punched her in her head. Once that happened, he was taken down by security & she was rushed out. That shit is crazy. I heard about it on the radio yesterday but forgot to look it up when I got home..
