It's time for Kourtney Kardashian to shine. After the news of sister Kim Kardashian's divorce from Kris Humphries and baby bro Rob Kardashian's second-place victory on "Dancing with the Stars", the eldest sister shared that she is pregnant with baby number two.

"Scott [Disick] 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 said in a statement to E! Online. Kourtney and Scott are already parents to 2-year-old Mason.

Kourtney took the pregnancy test five weeks ago and woke up Scott at 7 A.M. in the morning to deliver him the good news. "Now I'm nine weeks along," she told Us magazine. "You're supposed to wait 12 weeks to tell people, but I feel confident."

Scott himself was not shocked by the pregnancy, saying, "It wasn't like we weren't trying. We kind of just said, 'If it's meant to be, it'll be'. "

Kim, who recently said that she is content of being an aunt, wrote on her blog, "This is such a blessing and the whole family is beyond thrilled! I just know Mason will make the best big brother and I can't wait to meet my new little niece or nephew! Congratulations Kourtney and Scott. Xo."
