Whoa, Mama! Kris's B-day Surprise for Rob

It wouldn't be a Kardashian celebration without oversharing, would it? This time, the matriarch of the clan decided Rob Kardashian's birthday would be a great time to tweet a revealing picture of the 25-year-old...while in utero! Kris Jenner accompanied her famous children to Rob's birthday celebration in Las Vegas - who wouldn't want their mom along for a rowdy night out? - then tweeted her birthday wishes the next day. Included in the tweet was a 25-year-old picture of Jenner, topless and sporting a huge baby bump - inside would be the Dancing with the Stars runner-up. She wrote, "Happy 25th birthday to my wonderful, handsome son, Rob!! Rob, you are the best son a mother could ask for and you make me proud every day. I love you so much!!"
