Family celebrating new arrival
Kardashians are thrilled to have a new arrival in the family.
Kourtney's younger sister Kim Kardashian, who dates New Orleans Saints player Reggie Bush, took to her Twitter page to share the news with her fans and friends.
She tweeted before the birth: “I'm really excited [for the birth].'' The reality star, who was on the red carpet outside the Seminole Hard Rock Hotel & Casino Saturday night, wrote: “I'm definitely going to be a spoiling aunt.”
After the birth of the baby boy, she tweeted: “I'm an auntie! My little Mason Dash Disick is here! We are so happy.”
Pregnancy was a shock
Kourtney, the oldest of the three Kardashian sisters who appear on the E! Network shows "Keeping Up With the Kardashians" and "Kourtney and Khloe Take Miami," announced her baby news in August.
She opened up about her pregnancy during an interview with Ryan Seacrest of E! News on August 12. She told Ryan at the time that she was shocked after a home pregnancy test showed a positive result.
"I found out I was pregnant," Kourtney told Ryan. "We were in the Everglades and I kept feeling nauseous and sick and I just kept thinking, like, something wasn't feeling right. I've never missed a period in my [life]."
"I took like 20 tests," she stated. "I went to the doctor and he confirmed the news and I was just so shocked."
In October, she told E! News: "A boy is definitely needed in this family! Scott and I are thrilled to add a little boy to the bunch."
Kourtney and Scott as a couple
Kourtney and Scott dated on and off before breaking up in January. Despite the break-up, the two were spotted spending time together. In July, the pair was spotted hanging out in the Hamptons. At the time, she declined to confirm if they are an item again. "You're going to have to see on the show," she said, referring to her new reality show "Kourtney and Khloe Take Miami".
