Happy one-month birthday, Penelope Scotland Disick! The newest member of the extended Kardashian family made her big arrival just a few weeks ago, and she has already landed her first magazine cover. Kourtney Kardashian poses with her baby girl and 2-year-old son, Mason, on the latest cover of Us Weekly.

"Nothing could prepare me for how hard I fell in love with her," Kardashian told the magazine, in her first post-pregnancy interview.

Kardashian and her beau, Scott Disick, welcomed Penelope on July 8 in Los Angeles, and the entire family -- whom the world has gotten to know thanks to their various E! reality shows, including "Keeping Up With the Kardashians" -- was thrilled to add another member.

"Scott and I are overjoyed to welcome our precious angel Penelope Scotland Disick into our lives. We are forever blessed. Mommy and baby are resting comfortably," Kardashian told E! News when announcing Penelope's birth.

Aunt Kim Kardashian took to her Celebuzz blog to share her excitement about having a baby niece.

"Kourtney gave birth to a beautiful baby daughter on Sunday and the whole family is so thrilled to finally meet her!" she wrote. "She is absolutely perfect! I am so excited to be an aunt again and can’t wait to spoil little Penelope."

Kardashian has kept a very low profile since becoming a mom again, and many industry insiders were curious to see which magazine would shell out for the first photos of Kardashian's baby girl -- and how much Kardashian could make from selling the photos.

"She will be lucky if she gets $20,000 to $30,000 for the pictures," an editor told HuffPost's Rob Shuter last month. "The Kardashian craze has been over for some time now. Now a picture of Tom and Katie is worth more."
