Kourtney Kardashian took younger sister Kendall Jenner along for the ride when she and Mason made a Starbucks run Saturday in Calabasas.
See what those long-legged Jenner genes will do to a person -- 15-year-old Kendall is a foot and a half taller than her older sis!
Wonder if Mason will take after his slightly taller dad Scott Disick or if the Kardashian genes trump his father's!
