Just last week it was heavily reported that Kourtney Kardashian, the oldest of the famous sisters, is pregnant with her third child.

The reality TV star has finally confirmed the speculation by telling her longtime love Scott Disick in a preview clip of 'Keeping Up With the Kardashians,' which was shown following Sunday's (June 8th) episode.

The big news is revealed when the couple retreat to their luxurious walk-in wardrobe, with Kourtney simply telling Scott, "I'm Pregnant."

His reaction is quite hilarious, while looking very surprised the 31 year-old replies, "What? Holy [bleep]!"

The pair, who have been together for seven years, are already parents to a son, Mason, 4, and a daughter, Penelope, who is 2 next month.

Although this is the first time the 35 year-old's third pregnancy has been confirmed, "Multiple sources" already revealed the news last Wednesday (June 5th).

"She is only a few months along," an insider told Us Weekly, who first broke the story.

The celebrity magazine was also informed that Kourtney is already showing a pregnancy glow, according to a guest at the Trump SoHo hotel, where she stayed after returning home from attending Kim and Kanye's wedding in late May.

"Kourtney looked really pretty. She had a nice flush on her cheeks," said the guest.

"It was planned," another source told the gossip magazine. "[Kourtney] wants to have a handful of kids."

Loyal fans of the reality show would already know Kourtney's view on birth control, back in 2012 she stated on an episode that she is going to stop it forever, so her pregnancy news may have not been a shock.
