Kourtney Kardashian is showing off her new baby girl, Penelope Scotland Disick, on the latest cover of Us Weekly. Penelope, along with her older brother Mason, appears alongside her mother on the most recent edition of the magazine's cover.

In an exclusive interview with the magazine, the "Keeping Up With The Kardashians" star opens up about what her new baby girl means to her and the rest of the Kardashian-Disick family.

"Nothing could prepare me for how hard I fell in love with her," the DASH co-owner told the magazine.

In the new issue, the reality star, 33, and Disick, 29, also open up to Us about Penelope's delivery, how Mason is adjusting to the latest addition to the family and even why Scott is afraid to change Penelope's diaper.

Kourtney and boyfriend Scott Disick welcomed Penelope Scotland back on July 8 at Cedars-Sinai Medical Center in Los Angeles. She weighed in at 7 pounds, 14 ounces.

While Penelope is already one-month old, fans of "Keeping Up With the Kardashians" are already buzzing about birth details revealed on the show.

Just last week, the pregnant Kardashian hinted to her sisters on the show towards having a natural water birth. "I think it's important to talk to my sisters when I have a big decision to make," she wrote about why she asked her sisters for their advice. "Even though at the end of the day, it's my own choice, it's good to hear everyone's view and keep that in mind when I make my final decision."

Kourtney revealed to the world in November that she was pregnant for a second time. Several months later, she announced that she was having a girl. "We feel so blessed to be having a little girl and to be able to share this new experience with Mason," she tweeted.

Shortly before giving birth, Kourtney announced she wasn't sure she was willing to include the birth on one of her hit E! shows this time around. "I don't know," she said in an interview on "The Tonight Show." "We're gonna film it again ourselves, and honestly, my experience last time was so peaceful and calm and everything you don't see in the movies. And I really wanted to share that with people so they knew it doesn't have to be a crazy screaming session."
