Sam Heughan and Caitriona Balfe were spotted at a rugby game recently. They play the role of a husband and wife in "Outlander." They have always been rumored to be in a romantic relationship because of their off-screen friendship and their steamy scenes in the show. But the duo is nothing but close friends.

The pair was so close and they cuddled closely for a selfie as reported by People. Balfe was holding a drink and both were grinning. People that do not know them personally will assume that they are lovers. But the truth is they are just the best of friends. Heughan has a girlfriend named McKenzie Mauzy who walked with him at the pre-Oscars red carpet.

According to the actress who plays the role of Claire Frazer, the 36-year-old actor is her best friend since the time they met. They get along and she finds him very generous.

The two actors informed that they are tired of the constant inquiries if they are in a relationship. But they could not blame the public because they have such an amazing on-screen chemistry. 

The Cut reported that Heughan shared the cute selfie on his Twitter account captioned, "Thank you @THESTORMERS What a result!!!!! and so good to meet "4Ball" @iamSivN @caitrionambalfe."

Sam Heughan plays the second husband of Caitriona Balfe's character after she was transported to a mysterious world. In the other world, she is the wife of Frank and an M16 officer who became an Oxford historian.

Claire Randall Frazer's life became complicated because of her involvement with two different men. She married Frazer, who has a complicated past but has a god sense of humor, in order to survive. But as time goes on, she feels her world being torn apart. Season 3 of "Outlander" will air on April 1, 2017, on Starz.
