New York City is currently experiencing an intense heat wave, and Kendall Jenner and Gigi Hadid aren't helping cool things down. The stunning supermodels [1] couldn't have looked less bothered by the humidity when they stepped out for a cute outing in Manhattan on Sunday. Kendall showed off her toned tummy in a pair of black shorts, a crop top, and a printed jacket, while Gigi sported a lingerie-inspired dress [2] and a baseball hat. Of course, the outing is just the latest we've seen of the two so far this Summer. While Gigi has been spotted out [3] with her on-again boyfriend, Zayn Malik [4], Kendall has been living in bikinis [5], showing off her nipple piercing [6], and bonding with brother-in-law Kanye West [7]. We already can't wait to see what they get up to in August!
