Little Mason Disick has a sister! 33 year-old Kourtney Kardashian gave birth to her second child at the Cedars-Sinai Medical Center in Los Angeles yesterday.

She and partner Scott Disick are ecstatic at the arrival of their baby girl, who tipped the scales at 3.5 kilograms.

"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," she said in a statement to the media.

Kris Jenner told E! News that the new arrival looks just like her big brother. "It was great. She had an easy delivery," matriarch Kris Jenner said. "[Penelope] is so cute. She looks just like Mason. She's so beautiful. We are so happy."

Mason's birth was filmed and subsequently included in the hit show, Keeping up with the Kardashians. So the big question is, will Penelope's birth make it into the new season? If so, the show on E! Entertainment could see its best ratings to date with not only the addition of Penelope, but rapper Kanye West too.
