Kourtney Kardashian is pregnant.

The reality star and her partner Scott Disick - who already have children Mason, four, and Penelope, 23 months, together - will reportedly welcome their third child into the world in December.

"It was planned. Kourtney wants to have a handful of kids," an insider said.

Another source added: "She is only a few months along."

The 35-year-old was said to have a radiant pregnancy glow about her when she and Disick stayed at the Trump SoHo hotel in New York after returning from her sister Kim Kardashian's wedding to Kanye West in Italy last month.

A source said: "Kourtney looked really pretty. She had a nice flush on her cheeks."

Kourtney and Disick are said to have decided not to find out the gender of their unborn baby.

An insider told the new issue of Us Weekly magazine: "They don't know the gender yet. They just want the baby to be healthy."

The mother-of-two recently credited prioritising with helping her balance work and family life, and said her kids will always come first.

Asked how she juggles her schedule, Kourtney said: "Knowing my priorities. Nothing comes before my children. I find that putting everything else in order of importance also helps to get everything done."
