NEW YORK – Kourtney Kardashian (kahr-DA'-shee-an) has a baby on the way.

The 30-year-old reality TV star said in an appearance Thursday on NBC's "Today" show that she's due in December. Kardashian says the father is her on-again boyfriend Scott Disick, who appeared on the E! series "Keeping Up With the Kardashians."

Kardashian says she and Disick are "really happy" being together again. They broke up last year on the show.

Kardashian appears with her family on "Keeping Up With the Kardashians." She and her sister Khloe co-star in the E! spinoff show, "Kourtney and Khloe Take Miami."
