Kourtney Kardashian: Christmastime Arrival!

Pregnant reality star Kourtney Kardashian and younger sister Khloe head out of the Howard Stern Show in New York City on Thursday (August 13).

Kourtney and entrepreneur boyfriend Scott Disick, don’t expect their first child until Christmas but Kourtney has already experienced some physical changes.

“My boobs got huge right away,” Kourtney told People. “They got so sore, that if anyone even brushed up near me, I would scream. I’m really embracing [my pregnancy]. I feel like it’s such a beautiful thing, that every woman who goes though it, should embrace it. I think if you’re naturally skinny, and pregnant, and that’s how your body is, that’s fine.”

The new summer series, Kourtney & Khloe Take Miami, kicks off TONIGHT (August 16) @ 10PM ET/PT on E!.
