Kim Kardashian is cementing her status as Queen of the Selfie by releasing a book of her best shots, called Selfish.

The reality TV star and wife of Kanye West is well known for posting regular snaps of herself, including a few of her own bottom, on social media sites.

Now, she is immortalising a "best of" collection of the snaps in print according to The Sun and reckons there are actually some selfies that have not made it onto the internet, promising some never-before-seen photos including private shots she has sent to rapper Kanye.

She said: "I've accumulated so many selfies that no one's seen over the years and there's even a section I've sent Kanye, really racy ones."

Anyone who thought taking that infamous bottom selfie, or belfie, was easy will stand corrected after seeing the book - Kim says it took her a while to get the perfect photo and the outtakes will be included in her picture book.

She explained: "It took 10 selfies to get that one, so I'm putting in all those that didn't make it."
