Kourtney Kardashian and her sweetie Scott Disick have added to the famous reality show clan.

Daughter Penelope Scotland Disick arrived Sunday at Cedars-Sinai Medical Center in L.A. She weighed in at 7 pounds, 14 ounces. She joins big brother, Mason, 2.

"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," Kourtney, 33, who had an all-natural birth, tells E! News.

"It was a great. She had an easy delivery," matriarch Kris Jenner tells E! "[Penelope] is so cute. She looks just like Mason. She's so beautiful. We are so happy."

Sister Kim posted a note on her blog, saying, "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"

And yes, the delivery was filmed. Stay tuned for that.
