Sam Heughan and Caitriona Balfe [1] play one of the hottest couples on TV, and while many Outlander [2] fans wish they were also dating in real life, the sad truth is Sam is already taken [3]. The actor was first linked to actress MacKenzie Mauzy in 2015 when he attended her 27th birthday bash [4], but it's still unclear when they officially started dating. The two have a habit of keeping their love life private; the couple rarely posts photos together on Instagram and they rarely attend red carpet events together. Even when Sam was asked if he was in a relationship [5] in a 2015 interview, he coyly replied, "I might be." Keep reading for a look at all the pictures of Sam and MacKenzie we could get our hands on.
