Pregnant reality star Kourtney Kardashian is expecting another baby boy with her partner, Scott Disick. The baby will be the couple's third child.

Aside from the baby Kourtney is carrying, the couple is also parents to 5-year old Mason and 2-year old Penelope.

The 35-year old celeb revealed the news during an episode of the reality show spinoff, "Kourtney and Khloe Take the Hamptons."

And who else but adorable Mason was the first to break the happy news to the rest of the family. The memorable announcement was all caught on camera by Kourtney's sister, Kim Kardashian-West.

People magazine reported that aside from being extremely happy about the baby news, Kardashian feels that another boy would be the perfect addition to their growing brood.

Scott, however, didn't seem too excited while the sisters screamed for joy, mumbling that he was actually nervous about it.  

Kourtney's sister Khloe asked him why he didn't seem excited. He slipped and said that he wasn't initially excited about the news, and that he was actually hoping for another girl.

He immediately took back what he inferred, saying "No, I'm fine now. I'm excited."

Mason had initially wanted another baby sister as well, but seems to have come around to the idea of having a baby brother, especially after Khloe pointed out that he could "boss him around" because he was the eldest of the siblings.

Kourtney, on the other hand, seems excited not only by the baby, but how pregnancy has transformed her body.

Posing nude for DuJour magazine, Kourtney said that pregnancy makes her feel "empowered and beautiful".

Scott, on the other hand, wants to totally clean up his act - for his and his family's sake.

With Scott trying to avoid the temptations of alcohol and partying, Kourtney shared, "Scott avoiding putting himself in bad situations is definitely something new and I'm really proud of him."
