Kim Kardashian counting down to baby's arrival

Kim Kardashian is counting down the days to her baby's birth.

The 32-year-old 'Keeping Up With The Kardashians' star - who is set to welcome her first child in early July with her rapper boyfriend Kanye West - admits she is 'nervous and anxious' about motherhood but is grateful to her mother Kris Jenner and older sister Kourtney, 34, for inspiring her to be a great parent.

In a special Mother's Day post on her blog on Sunday (12.05.13), the reality TV star wrote: 'Mother's Day is one of my favourite holidays because it's a special day to honour 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.'

Kim then paid tribute to other expectant mothers, as well as Kris, her grandmother MJ and her Kourtney, who has two children, Mason, three, and Penelope, 10 months, with her boyfriend Scott Disick.

She wrote: '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. Motherhood is a gift and I know after watching my mom do it, it's not easy especially when trying to balance a career. I'm honoured to follow in her footsteps and make her proud like I am of her.

'Kourtney, my sister, best friend, and mentor has also taught me so much about motherhood from being the most incredible mom to Mason and Penelope. She is super woman with her ability to effortlessly balance work with taking care of two amazing kids and I am so lucky to have her as my guide and confidant as I too become a mother.

'And also my wonderful grandma MJ, such a strong and inspirational woman in my life! I love you so much!

'Make sure to tell your mom how much you appreciate her, not just on Mother's Day but often. We love our mommas! To all the expecting moms and moms out there, have a blessed day! Xo'
