She posted several nude shots to Snapchat, showing off her new tan.
The Selfish author also had some fun wishing her assistant, Stephanie Sheppard, a happy birthday on Instagram.
“Happy Birthday@steph_shep I love this pic of us!” she captioned a photo of herself from Mexico in tiny bikini bottoms with Sheppard’s reflection on the glass door.
She shared another self-deprecating Mexico pic of herself flaunting her curves with Sheppard chowing down behind her, writing, “Seriously @steph_shep thanks for always having my back and eating all my left overs so they don’t go to waste!”
Kardashian took one last jab at her assistant, posting a pic with Kardsahian’s famous booty facing the camera, writing, “In all seriousness I’m going to be totally selfless for this one last post. Thanks for being my main bitch! Happy Birthday!”
