The reality TV star has put her self-snapped images together into a book titled Selfish, but fans were banned from taking their own 'selfies' at her signing event at a Barnes & Noble store in Manhattan.

New York Daily News reporter Reuven Blau managed to break the rules by snapping a quick shot with Kardashian, and writes, "There were strict rules against engaging with Kardashian at all. Nothing would be allowed, we were told...

"'No photos or inscriptions!' a beefy security guard repeatedly warned. I had other ideas. The plan was to secretly yank out my phone just as I finally made my way up to the desk where she was signing... My editor needed that shot - and my wife told me not to bother coming home if I muffed it... The resulting photo isn't perfect - I'm sort of looking in the wrong place and Kardashian is out of focus."
