Kourtney Kardashian is having a boy. Kourtney finally disclosed the sex of her baby yesterday, and it looks like the Kardashians are going to be purchasing all sorts of blue-themed clothing and toys in the next few weeks. Wonder if they’ll name him Kristopher or Karl. Perhaps Klaus.

more photos of Kourtney and her stage Mom after the hop…

A source told People.com:

“Kourt and Scott are psyched about having a baby, but having a boy is really exciting for them. She can’t wait to buy all sort of boy’s clothing. And [her brother] Robert is also eager to have a little nephew…”

Kourtney anticipates she will have the shower to end all showers, with Kris Jenner stage Mom-ing it behind the scenes. We’re sure they’ll sell the photos to OK! or usmagazine.com, so we’ll its likely you’ll see them in the coming weeks. We know you are as thrilled as us.
