Thanking her grandmother, her mother of six, Kris Jenner, and sister Kourtney, Kim wrote: "Mother's Day is one of my favorite holidays because it's a special day to honor my role model and best friend. As I'm counting the days until I finally get to be a mother, I'm a bit nervous and anxious but also excited knowing that I learned from the very best."

"My mom is a strong and ambitious career woman that despite her busy schedule and the millions of things she has going on, she still manages to put family first and continues to look out for us every day," she explained. "I'm honored to follow in her footsteps and make her proud like I am of her. And also my wonderful grandma MJ, such a strong and inspirational woman in my life! I love you so much!"

She is super woman . . . and I am so lucky to have her as my guide and confidant as I too become a mother."
