You know your couple name is official when it is decreed as such by a supermodel. So when Gigi Hadid and Joe Jonas (rocking a furry coat, for some reason) popped up on Cara Delevigne's Instagram feed, the pro catwalker introduced the world to "G.I. JOE." She even conveniently provided a hashtag for all your future social media needs.
While Joe and Gigi have remained pretty quiet about their relationship status, Joe's younger brother, Nick, recently opened up about the A-list pair. "I like them together. It's a good thing," he told E! News last week. "Joe and I are best friends. We're each other's support system and closest friends, so naturally I'm gonna see a lot of her because they're together and it's great. I'm really happy for them. I think they seem very happy together and it's good."
