So who did Sam choose to be his real-life partner?

Sam Heughan and Caitriona Balfe’s undeniable chemistry in “Outlander” made people believe that the co-stars may have already taken their on-screen romance off-screen.

Meanwhile, the “Outlander” fans and Sam-Caitriona shippers did not initially like the idea of the “Outlander” actor being linked with another woman, so they took their frustration out on Mackenzie Mauzy.

Many were clearly unhappy after realizing that Sam Heughan has a real-life girlfriend which led them to attack the 28-year-old actress online.

Although the shipping of Sam Heughan and Caitriona Balfe was sweet and harmless at first, it did get to the point of cyber-bullying. The “Outlander” season 3 actor has had enough of the nonsense and finally took to social media to address the issue and to end all the harassment thrown at his girlfriend.

“Shameful behaviour by many on social media recently,” Sam Heughan tweeted at the time. “It's disgusting and needs to stop. Spineless bullying. Stop. Now.”
