The family shot the pictures on Aug. 2 at Kardashian and Disick's home in Calabasas, Calif. The 33-year-old reality star dished to the magazine about what life has been like with her new bundle of joy.

"Nothing could prepare me for how hard I fell in love with her," Kardashian said. "With Mason, we have such a love affair that I never knew existed. I didn't expect it to happen again. It's such a magical feeling."

Kourtney added that Mason, 2, is just as in love with his new sister, and he's already developed a strong bond with 6-week-old Penelope.

"He's adjusting to the whole thing so well," she said. "He calls her 'sister.' He gets mad if anyone calls her anything else. People will be like, 'What's your sister's name?' And he'll say, 'Sister!'"

So will Penelope's birth be featured on an upcoming episode of "Keeping Up With The Kardashians?" The family hasn't decided yet, but Kourtney said the footage is there if they choose to use it.

"We did tape it with our cameras, and Scott was taping some of it on his iPad," Kardashian explained. "I could see cameras from all angles!"
