So much fun! Kourtney Kardashian, 41, posted a cute Instagram pic of her daughter Penelope Disick, 7, and niece North West, 6, reuniting for a fun day in the sun on Saturday, May 2. It looked to be a great minds think alike kind of deal, fashion wise, for the youngsters as they twinned in their adorable matching outfits! Both of the girls wore white tank tops and colorful sweatpants that were different variations of the color pink.
