Justin and Hailey became more than friends over the holidays in 2015 when they jetted off to a tropical location to ring in the New Year together. Justin posted a snap of the pair sharing a passionate kiss, but things fizzled out soon after they returned. Hailey told E! News that April, "We are not an exclusive couple. He's about to go on tour. Relationships at this age are already complicated, but I don't really like to talk about it because it's between me and him."
