Khloe Kardashian is a proud sister as she celebrates Kim Kardashian’s biggest milestone.

The 40-year-old reality star took to Instagram and shared a series of pictures from Kim’s graduation ceremony held after she passed from her law program.

“‘What, like it’s hard?!’ Congratulations my baby Keeks!!! My sister is done with her law program!!,” Khloe wrote in the sweet caption, alongside a picture of Kim at the podium and several pictures of their whole family.

“I am so beyond proud of you. Your level of discipline and ambition is truly motivating. You have a level of drive that feels almost unbelievable—and undeniably powerful,” the Good American cofounder added.
