Kim Kardashian Lends Pregnant Sister Kourtney A Hand With Mason

Lucky Mason Dash Disick -- not only is the two-and-a-half-year-old part of a family worth millions and millions of dollars, but he gets to ride in the arms of mom Kourtney and aunt Kim Kardashian -- talk about the royal treatment!

Kim and Kourt lunched at Tra Di Noi in Malibu on Sunday, and they were also joined by Mason's daddy Scott Disick, who seemed more than happy to let K & K take over parenting duties. Kourtney, who confirmed her second pregnancy in November, is starting to get enormous, so we're guessing she was happy to hand off her little boy to Kim, who was snapped giving him a boost on the playground so he could reach the monkey bars. Aww, what a doting auntie!
