Kim Kardashian, a first-time mother-to-be, may not be a mom yet, but she was thankful on this Mother's Day.

In an adorable note she shared on her website, Kim wrote to the mother figures in her family: her grandmother, her mom Kris Jenner, and her sister Kourtney.

"Mother's Day is one of my favorite holidays because it's a special day to honor my role model and best friend," Kim wrote. "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."

She went on to thank her own mom and grandmother. 

"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," Kardashian 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!" Kim wrote. "I love you so much!"

While she has these mother figures in her life, Kim also gave credit to sis Kourtney for helping herself and boyfriend Kanye West along the way as they await the arrival of their first child in July. 

"My sister, best friend, and mentor has also taught me so much about motherhood from being the most incredible mom to Mason and Penelope," Kim shared. "She is super woman . . . and I am so lucky to have her as my guide and confidant as I too become a mother."
