Kourtney Kardashian, the eldest sister in the fam, has announced that she and boyfriend Scott Disick are pregnant once again! Yes, Baby Mason is a big-brother-to-be.

"Scott and I are so excited to announce that we are expecting our second child and are thrilled to be expanding the love in our family," she tells E!.

If you watched the premiere of "Kourtney and Kim Take New York" on Sunday (Nov. 27), you know that Kourtney takes her role as a mom very seriously. She doesn't even let Mason play with plastic toys for fear of nasty chemicals! She's sharing her expertise in a "mommy blog" on E!, because there is a major shortage of celebrity mommy blogs these days.
