Scott Dissick, Kourtney Kardashian

Kourtney Kardashian is adding to the clan — she's pregnant with baby No. 2.

Kardashian and on-again-off-again boyfriend Scott Disick announced the news early Wednesday, first reported by Us Weekly.

"Now I'm nine weeks along," she said. "You're supposed to wait 12 weeks to tell people, but I feel confident."

This will be the couple's second child together. Their son, Mason Disick, was born in December 2009.

"It wasn't like we weren't trying," said Disick, 28. "We kind of just said, 'If it's meant to be, it'll be.'"

Kardashian, 32, and Disick have been together (on and off) for five years. On Sunday's premiere of Kourtney and Kim Take New York, the E! reality star made it clear that they were not in a relationship — and the two even slept in separate bedrooms.
