'How sweet!' Kim Kardashian shares rare photo with Saint AND North as she gives fans a sneak peek at new edition of her selfie book

Kim Kardashian has shared a rare photo with her two children, North and Saint West.

The 35-year-old posted the snapshot to Instagram on Friday night and revealed that it is a sneak peek from the new edition of her selfie book.

'Here's a pic from my new edition of SELFISH out in October. How sweet is my Saint at 2 months old & my little North,' she wrote.

While Kim often shares photos with North and has begun posting more pictures of Saint on social media, it is rare to see both children in the same frame.

The photo appears to have been taken in February, when the reality star was seen sporting a blonde wig worn in braids.

In the snapshot, Kim can be seen wearing a black turtleneck and cradling her baby boy while pouting at the camera.

Little Saint is shown clad in a white onesie and snoozing in his mother's arms as they sit on a sofa.
