Kardashian celebrated her birthday early in order to tape a special for E! Network.

Her siblings and her mother, Kris Jenner, threw her a surprise party that was modeled after all of the birthdays the SKIMS founder had in the past.

“You know I’m a sentimental person and this party was the most special. They re-created all of my special birthdays throughout my life from looking at all of our old home videos,” Kardashian shared on social media.
