Sam Heughan and Caitriona Balfe are best friends in real life and the Outlander stars showed off their cute banter on Twitter on Friday (June 2) after a tennis match!

The 37-year-old actor, who just landed a hot new movie role, shared a photo of him and Caitriona, in which he has a big smile on his face and she is holding up her middle finger.

“‘New Balls Please!’ 🎾🎾 I’ll let @caitrionambalfe tell you the score… #AnyOneForTennis #CallMeJamieMurray,” Sam captioned the photo. He added, “Wimbledon next Balfe?”

“Yes well…. when one plays dirty …. #thatsallimsaying,” Caitriona replied, to which Sam said, “How dare you, a gentleman never cheats… unless it’s to win #justNotCricket.”

Don’t you just love these two?!
