Kardashian pregnant with first child

Kourtney Kardashian has announced that she is expecting her first child.

The Keeping Up With The Kardashians star told Ryan Seacrest on E! News that she had discovered the pregnancy while filming her new reality show Kourtney And Khloe Take Miami.

"We were in the Everglades and I kept feeling nauseous and sick and I just kept thinking, like, something wasn't feeling right," she explained.

"I've never missed a period in my [life]. I took like 20 tests. I went to the doctor and he confirmed the news and I was just so shocked."

Kardashian, 30, declined to reveal who the father was, although she has previously been linked to Scott Disick. The baby is due in December.
