Kourtney Kardashian has announced she is pregnant with baby number two.

Kourtney Kardashian, 32, has revealed that she is just nine weeks into her second pregnancy.

The reality star and her partner Scott Disick, 28, already have a son Mason, who turns two on December 14.

In a statement to E! Kourtney Kardashian said: “Scott and I are so excited to announce that we are expecting our second child and are thrilled to be expanding the love in our family.”

Kourtney Kardashian first revealed the news to this week’s issue of Us Weekly.

The older sibling of Kim and Khloé Kardashian told how she woke Scott Disik up at seven o’clock after taking a positive pregnancy test to share the news.

Kourtney Kardashian was so excited, she couldn’t wait the traditional amount of time before sharing it with the world.

“Now I’m nine weeks along,” Kourtney Kardashian tells Us Weekly.

“You’re supposed to wait 12 weeks to tell people, but I feel confident.”

In an episode of Keeping Up With the Kardashians in July, Kourtney Kardashian was seen clashing with mother Kris Jenner after she mentioned that she and Scott Disik were considering trying for another baby.

While their first child Mason was a happy surprise, Kris Jenner is adamant that the couple should be married before thinking about expanding their family.

In the episode, Kourtney Kardashian is insistent that she will marry if and when she chooses, and admits the reason she is hesitant to walk down the aisle is because she doesn’t want her children to go through a parents’ divorce they way she did as a child.

Kourtney Kardashian and Scott Disik have broken up a number of times over Kourtney’s disapproval of her partner’s hard partying and anger issues.

During their stint in Miami last year, Kourtney Kardashian ordered Scott Disick to leave her and their son alone after he turned violent and smashed a mirror, telling him “I love Mason more than I love you”.

Scott Disik has since worked out his issues and has said he has no problem marrying his long-time love.

Scott Disik even proposed to an unimpressed Kourtney Kardashian in the final episode of last season’s Kourtney and Kim Take New York.

Turning down his offer of marriage during dinner on their four-and-a-half year anniversary in April, Kourtney Kardashian asked: “Things are so good right now, why would we want to change that?”

And headstrong Kourtney Kardashian has clearly decided not to fulfill her mother’s wishes to get married before falling pregnant again.

“It wasn’t like we weren’t trying,” Scott Disick says.

“We kind of just said, <<If it’s meant to be, it’ll be>>.”

Another member of the family who may not be thrilled over the news is Kourtney Kardashian’s sister Kim.

Kim Kardashian, 30, who recently separated from husband Kris Humphries after just 72 days, said in a magazine interview this week that she feels her dreams of children may be dashed.

“At first I was like, I want six kids. Then I went down to four, then I was down to three, and now I’m like, maybe I won’t have any.”

“Maybe my fairy tale has a different ending than I dreamed it would.”

The Kardashians younger sister Khloé, who married basketballer Lamar Odom in 2009, has also revealed that she is concerned about her difficulty in conceiving.

Speaking on The Today Show last month, Khloé Kardashian, 27, admitted: “It’s so hard. I never knew about ovulation and the limited amount of time that you have to get pregnant.

“I never knew about that. No-one ever taught me that.”
