Kardashian usually stays out the headlines compared to her younger sisters and brother, but several insiders revealed in the newest issue of Us Weekly  that she's now expecting a child.

"She's only a few months along," one source said while the other added,"It was planned. Kourtney wants to have a handful of kids."

An insider also said that the couple doesn't know the gender nor do they have a preference.

"They want the baby to be healthy."

Disick and Kardashian are already parents to 4-year-old Mason and Penelope, who will be 2 years old next month. Kardashian is said to have had a pregnancy glow when she and Disick cozied up at the Trump SoHo hotel after her sister, Kim's wedding to rapper Kanye West.

"Kourtney looked really pretty. She had a nice flush on her cheeks."

Kourtney recently revealed that she has no plans to go on birth control.

She said, "I need to see what it's like when I have two, but [having kids] is what life is about. I'm not going on the pill. I don't believe in it anymore!"

The baby is due in December. The journey surrounding Kourtney's pregnancy will most likely be seen on the newest season of Keeping Up With The Kardashians. In a newly released clip, Kourtney urges her younger sister, Khloé, to move out of her and her estranged husband Lamar Odom's home. However, she takes it a little too far when she offers to remove all of Khloé and Odom's pictures from the frames.
