Reality TV star Kim Kardashian is set to update her selfie book Selfish.

The Keeping Up With the Kardashian star – who has children North, 3, and Saint, eight months, with husband Kanye West – is adding two additional chapters to her 2015 book of images, reports

She teased on Instagram: "New Selfish alert! Two more chapters added! Dropping soon!"

Kim – whose original book featured almost 500 pictures she’d taken of herself – recently teased she is planning to share a nude selfie online to show off her trim post-pregnancy physique.

She said: "Have I posted a nude selfie since I lost all my baby weight?

"I don’t think so. Get ready."

The 35-year-old star plans on celebrating losing 70 pounds by sharing a nude picture because it makes her "feel good" about herself and it boosts her confidence.
