Say hello to a new generation of reality stars! Kourtney Kardashian, 33, welcomed her second child with long-term partner Scott Disick, 29, a baby girl named Penelope Scotland Disick, who was born early Sunday morning at Cedars-Sinai Medical Center in Los Angeles.

Penelope weighed in at 7 pounds, 14 ounces, and Kardashian matriarch Kris Jenner, 56, told E! News that Kourtney "had an easy delivery."

"Scott and I are overjoyed to welcome our precious angel Penelope Scotland Disick into our lives," Kourtney said in a statement to E!. "We are forever blessed, Mommy and baby are resting comfortably."

Of her new granddaughter, Penelope, who joins Kourtney and Scott's first child, Mason, 2, Jenner also added that she "is so cute. She looks just like Mason. She's so beautiful. We are so happy."

Which leaves the famous Kardashian sisters to chime in. "I'm an auntie again!!!!!!!!!!!! As I'm sure you all know, my beautiful big sister gave birth yesterday to the most perfect baby girl you've EVER seen," wrote sis Khloe Kardashian, 28, on her blog. "The entire family is literally exploding with joy and have not stopped fawning over our new little girl. And Mason is already loving being a big brother! This is just such a special and happy time for my family."

Kim Kardashian, 31, who has most recently been in the news for her new relationship with Kanye West, 35, following her split from Kris Humphries, 27, followed suit on Twitter. "Welcome to the world Penelope Scotland Disick!!!!" Kim tweeted, with the requisite number of exclamation points.
