"Thanks for kicking my a** tonight!!!!" Khloe wrote to the Cycle House instructors in her caption. Hey, when you're posting pics together on social media, it's so on. Khloe has been hard at work on her fitness this summer and shared a photo with another gym buddy yesterday: her sister Kendall Jenner.
The model just got back from Paris Fashion Week and Khloe showed her some (interesting) love by licking her little sister's abs in this Instagram post of them in the gym. Is James Harden next to get the tongue on abs treatment?!
