Kylie Jenner, Gigi Hadid and Cody Simpson

Gigi Hadid, 27, has been a good friend of the Kardashian-Jenner sisters, being Kendall, 27, and Kylie, 25, the ones she hangs out with the most. Back in 2011, the latter had a brief romance with swimmer and songwriter Cody Simpson, 25, who started dating Gigi a couple of years after their breakup. Gigi and Cody had an on-and-off relationship that lasted two years. It seems the friendship between Hadid and Jenner did not have a negative impact, as the girls have posed together for the Instagram camera on multiple occasions ever since!
