Just a few hours after announcing that she's expecting her second child with husband Scott Disick, Kourtney Kardashian was spotted yabbering away on her cell phone as she ran errands in Hollywood.

X17online posted these photos of Kourt's baby bump yesterday, and she confirmed the good news this morning, tweeting, "Yes, Im pregnant! Now Im nine weeks along. Youre supposed to wait 12 weeks to tell people, but I feel confident."

Her sister Kim is "beyond thrilled" with the news, and Khloe wrote on her blog just now, "[M]y beautiful big sister Kourtney is expecting yet again! Can you believe it?! Masey is going to be a big brother! We are all so overjoyed by this wonderful news and are counting down the minutes until we get to meet the newest member of our family. Kourtney is the greatest mom in the world and I am so proud of the woman she has become. I cant wait to see her with a kid in each arm! Shell be a pro. LOL. And if this next baby is anything like Mason, then we will truly be the luckiest family in the world.
Congratulations, Kourt, Scott and Mason!!!! I love you all more than anything!"
