Kourtney Kardashian pregnant with third child

Looks like the Kardashians have even more to celebrate. Kim Kardashian just married Kanye West in a Florence, Italy, wedding extravaganza. And now...baby North is getting another cousin—Kim's sister Kourtney is preggers again.

Yes, it seems the Kardashian clan is growing...even bigger! Kourtney, 35, and her longtime boyfriend, Scott Disick, 31, are reportedly expecting their third child. Baby will join big brother Mason, 4, and sister Penelope, 23 months.

“She is only a few months along,” says a source for Us Weekly, adding, “[Kourtney] wants to have a handful of kids."

And whether it's a boy or girl makes no difference to the reality-star couple. “They don’t know the gender yet,” reports a source. “They just want the baby to be healthy.”

One last deet (so far): The baby's said to be due in December.

Though unexpected, this news isn't a huge surprise. Us says a witness reported Kourtney looking "flushed" when she returned to New York after Kim's wedding. And others have noted Kourtney's been abstaining from alcohol lately.

I'll be keeping an eye out for an official announcement on Kourtney's Twitter and Instagram feeds (in all that spare time I have at this end-of-school crazy time—wink!). In the meantime, off to add Kourtney to our Who's Pregnant in Hollywood gallery. See you there!
