The actress shared the news with Us Weekly, telling the mag she's nine weeks along. The E! reality star, 32, took a pregnancy test about five weeks ago and woke up boyfriend Scott Disick at 7am to break the news to him.

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

This will be baby number two for the unmarried couple. The pair's son Mason is 2 years old.
