A Kardashian-Jenner Family Tree

Once jokingly described by Kim Kardashian as "the best birth control ever," Mason Dash Disick is the cutie-patootie child of Kourtney Kardashian and Scott Disick. He lives in Miami with his parents, but is a frequent flyer — often "dashing" between Miami, L.A., Chicago, and New York City at a moment's notice. "My son is such a great little traveler already," Kourtney gushed to her blog fans. "He even has his own passport so he's prepared for any trip that may arise."
