The Kardashian sisters, Kim and Khloe, are filled with glee over their new niece Penelope Scotland Disick, who was born to oldest Kardashian sister, Kourtney.

The younger sisters took to their blog to gush about the new bundle of joy.

The middle Kardashian gal, Kim, wrote:

"Welcome to the world, Penelope Scotland Disick! Kourtney gave birth to a beautiful baby daughter on Sunday and the whole family is so thrilled to finally meet her! She is absolutely perfect! I am so excited to be an aunt again and can't wait to spoil little Penelope. I know Mason is going to be the best big brother in the whole world. Congratulations Kourtney and Scott. Xo"

Kim, who currently deals with an embarrassing and public divorce, has expressed how much she wanted her fairytale. She had an elaborately lavish wedding last year to Kris Humphries; the marriage lasted but only 72 days. The reality star has insisted in numerous interviews that she was really in love and that she really wants to have a husband and kids. She is now in a high-profile relationship with Kanye West.

The youngest Kardashian diva, Khloe, wrote:

"I'm an auntie again!!!!!!!!!! As I'm sure you all know, my beautiful big sister gave birth yesterday to the most perfect baby girl you've EVER seen - Penelope Scotland Disick! The entire family is literally exploding with joy and have not stopped fawning over our new little girl. And Mason is already loving being a big brother! This is just such a special and happy time for my family.

Khloe and her husband Lamar Odom have been trying for a baby for nearly three years. Odom has expressed that he first felt jealous of Kourtney's baby news.

Despite the sisters' marital issues and fertility difficulties, the family still finds joy for their big sis and the new baby.
