Kourtney was seen confirming the sex of her unborn child during an episode of Kourtney & Khloe Take The Hamptons, which was aired in the US last night.
During the show, fans were treated to a home video made by Kourtney's younger sister Kim Kardashian.
The clip showed Kourtney and Scott's eldest child, five-year-old Mason, unveiling a stick featuring a blue star - confirming that the couple are having another boy.
Kourtney and Scott are already parents to Mason and younger sister Penelope, two, and their third child is due later this month.
However, for weeks now there has been widespread rumours that Kourtney was in fact expecting a baby girl!
Last month, Kourtney looked seriously glam in all-black as she attended her first of two baby showers in Los Angeles.
The swish event was held at the luxurious Montage Beverly Hills Hotel and Kourtney was joined by her family members, including Kim who brought daughter North along with her.
Days later, Kourtney was pictured at her second baby shower, which was a much more casual affair!
Joined by her closest girl friends, Kourtney enjoyed a scrummy breakfast of waffles and cream one Sunday morning at iHOP (International House Of Pancakes) - and they all wore their pyjamas for the occasion!
Fans were left worried last month after Kourtney posted a cryptic message on Instagram, hinting at relationship troubles with Scott.
However, on Friday they were pictured hand-in-hand after leaving a lunch date in LA together.
Not long to go now...and we can't wait to see what Kourt and Scott call their new son!
