Aww, what a great auntie!
Yesterday Kendall Jenner hit the beach in Malibu, and the 16-year-old model/reality TV starlet spent most of her afternoon playing with sister Kourtney's adorable son Mason. Kourt laid low with her newborn daughter Penelope Scotland, but daddy Scott Disick was around to help with babysitting duties, as was Kendall's sister Kylie.
After some fun in the sun, the Jenner girls ran to Malibu Cafe to grab a bite, and Kylie posted a Twitter video of her older sister behind the wheel as the ladies sang along to Kanye West's single "Mercy"...
Auntie Kim would be proud!
