The same day that her son Mason Dash turned five, Kourtney Kardashian gave birth to her third child. The Keeping Up with the Kardashians star and Scott Disick welcomed their third child together. The baby, who’s name has not been revealed, joins brother Mason and sister Penelope.

“The family is freaking out with joy,” a source told E!News. “What an amazing coincidence,” of the fact that Kourtney’s third child was born the same day as son Mason. Kardashian is 35 and her longtime partner Scott Disick is now 31. Kourtney had announced on the most recent season of Keeping Up with the Kardashians that she was expecting, and later revealed the gender in her spinoff show, Kourtney and Khloe Take the Hamptons.

“I’m so happy we’re having a boy,” Kourtney said after finding out the sex of the child. “It’s going to be perfect for our family.” The reality television start also explained, “I love being pregnant in general,” to Fit Pregnancy in November. “This time I’m more tired than I was the other times. I think it’s because I’m always running around and working on different things. But I feel comfortable with how I look and feel. I find a pregnant body to be beautiful and an incredible reminder of what a woman’s body is made to do.”

Kim and Khloe Kardashian threw a swanky Breakfast at Tiffany’s-themed baby shower for their big sis last month at the Montage hotel in Beverly Hills, and Kourtney celebrated again a few days later at an early-Sunday-morning trip to IHOP with her best pals.

As for the new baby’s name, while pregnant Kourtney said she was stuck and wanted to wait until the child arrived to make the decision. In a recent Instagram post, Kourtney posted a photo with the caption, “Madly in love with my little Reign Aston Disick.”
