It’s a boy: Kourtney Kardashian and Scott Disick welcome their third child

Kourtney Kardashian has given birth to a baby boy – on the same day as her son Mason’s fifth birthday.

The Keeping Up With the Kardashians star – who already has son Mason, 5, and daughter Penelope, 2, with partner Scott Disick – welcomed the new addition on Sunday.

Clearly excited with the impending birth, the reality star took to Instagram on Saturday to post a picture showing a doll sleeping in a cot with the caption “Nap time! Someone's already using our new crib."

Kourtney, 35, recently posed naked for DuJour magazine to celebrate her pregnancy figure.

Speaking to DuJour she said: “To me, nudity is not something to be ashamed of. I’m not embarrassed of my body.

“I’m at my best when I’m pregnant. It’s such an amazing feeling, the transformation that your body goes through.

“There’s something about that that’s so empowering and beautiful and I just really embrace it.”
