The pair started dating in 2014 and have been private when it comes to their relationship. However, after getting married in 2015, Cameron gushed about her new husband to Instyle magazine, saying: "Getting married to him was the best thing that ever happened to me. My husband's the best. He's the greatest human being, and he's my great partner. Marriage is certainly hard, and it's a lot of work. You need somebody who's willing to do the work with you, because there's no 60-40 in marriage. It's 50-50, period. All the time."
