Kourtney Kardashian went onto Ryan Seacrest’s radio show On Air with Ryan Seacrest to tell the world she’s pregnant.

But, she hasn’t been spreading the news willy-nilly. Kardashian’s mother, Chris, actually coughed up the news to Seacrest and it took an additional two weeks for her to fess up to the American Idol host.

Who’s the daddy? Her hot beau, Scott “Scotty the Body” Disick. Kardashian had broken up with Disick in January of 2009 allegedly because he was cheating on her.

Kardashian admits she’s still getting used to saying she’s pregnant, but even tougher? Swollen breasts…like they needed a boost…not to mention huge waves of nausea.
