Khloé Kardashian and ex Tristan Thompson are making co-parenting work — and in matching outfits, no less. The former reality TV star, 37, and the NBA player, 30, stepped out to escort their daughter True, 3, to dance class in Los Angeles on Monday in color coordinated black outfits. Khloé wore a black tank and leggings with a matching black Prada fanny pack, while Tristan wore a black graphic tee and shorts.
