Here’s some news that the Kardashians can’t change their mind about: Kourtney Kardashian is pregnant with baby No. 2.

The eldest Kardashian sister and her boyfriend, Scott Disick, have revealed that they’re expecting a second child together. (Their first child, Mason Dash Disick, turns 2 later this month.)

“Now I’m nine weeks along,” Kardashian told Us Weekly. “You’re supposed to wait 12 weeks to tell people, but I feel confident.”

The 32-year-old “Kourtney and Kim Take New York” star said that she found out she had another bun in the oven after taking a pregnancy test about five weeks ago.

She said she was so excited about the results that she woke Disick up at 7 a.m. to give him the good news.

The couple of five years said that their new baby is not a surprise, unlike Mason, whose unexpected conception was chronicled during a Season 1 episode of “Kourtney & Khloe Take Miami.”

“It wasn’t like we weren’t trying,” Disick, 28, said. “We kind of just said, ‘If it’s meant to be, it’ll be.’ ”

Khloe Kardashian, took to her Celebuzz blog yesterday to write that big sis “Kourtney is the greatest mom in the world . . . I can’t wait to see her with a kid in each arm! She’ll be a pro. LOL. And if this next baby is anything like Mason, then we will truly be the luckiest family in the world.”
