Kourtney Kardashian and boyfriend Scott Disick welcomed a baby girl Sunday -- Penelope Scotland Disick, weighing in at 7 lbs, 14 ounces.

The 33-year-old star had an all-natural birth, according to E! News. The reality show star told her network: "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."

The baby was born early Sunday at Cedars-Sinai Medical Center.

So will the big moment be shared with Keeping Up With The Kardashian viewers, as Mason's birth was? Kourtney said on the Tonight Show a few weeks ago: "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" So we'll have to wait and see what the proud parents decide this time!

UPDATE - Kourtney's sis Kim posted this congratulatory message on her website:

    "Welcome to the world, Penelope Scotland Disick! Kourtney gave birth to a beautiful baby daughter on Sunday and the whole family is so thrilled to finally meet her! She is absolutely perfect! 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"
