Having just jetted in from a holiday in Mexico, US reality star Kim was spotted with four-year-old Mason in the exclusive Calabasas area of California.
The twosome headed to Barnes & Noble book store and, along with picking up several reads for herself, Kim bought Mason a new book too.
The little lad, who is the son of Kourtney Kardashian and partner Scott Disick, was then seen proudly clutching his gift as they made their way back to the car. Too cute!
Earlier this week, Kim and her husband Kanye were pictured soaking up the sun in their favourite holiday destination of the moment - Mexico.
The couple, who married in Italy in May, were joined on their trip by friends and spent their time relaxing and stuffing their faces with quesadilla!
Before they left, Kim shared a new bikini picture, which showed her laying on the edge of an infinity pool with her back arched towards the sky.
Posting it on Instagram, she commented: "I will miss you."
Don't worry, Kim, we sure you'll be back soon. After all, she and Kanye have enjoy three Mexican trips already - since June!
