Fans of Kourtney Kardashian became ecstatic as she revealed on the latest episode of 'Kourtney and Khloe Take The Hamptons,' that she and boyfriend Scott Disick will be having a baby boy.

In the episode, Kardashian shared a home video of them filmed by her sister Kim and also recounted the story of how her son Mason felt when he found out about his baby brother.

Kardashian said Mason helped announce the news to the family by showing them all a stick with a blue star, which meant a boy, instead of a red star which was for a girl. Mason admitted he wanted a baby sister though, but his mom was quick to turn it around. She said that a girl wouldn't be able to play aliens and Legos with him and he'll be able to boss his younger brother around and play rough with him, not like with Penelope.

Kardashian and Disick have three children thus far; Mason, who is turning 5; Penelope, 2; and the soon-to-come baby boy who is due sometime this holiday. However, Mason might end up sharing his birthday with his new brother as his birthday falls on Dec. 24.

Kardashian is excited and happy for the new addition, saying a baby boy will be perfect for her family. However, it was also noted in the episode that Disick looked intimidated at having another child when the announcement was made to the family, according to US Weekly.

E! News reports that during the ninth season of 'Keeping Up With the Kardashians', Disick wasn't thrilled when Kardashian told him they were having their third child. He responded to the news with "This ain't good," and even said, "You just keep suckering me into these kids."

However, on Sunday's episode of 'Kourtney & Khloe Take The Hamptons', when Kardashian's sister, Khloe, asked Disick if he was or was not excited about the baby, he quickly reassured them and said, "No, I'm fine now. I'm excited."
