Sam Heughan took to Twitter to pen a sweet happy birthday message to Outlander co-star Caitriona Balfe.
The Scots actor took to social media to celebrate Caitriona's 43rd birthday, telling fans they will be spending it together on set in Cumbernauld. The two became fast friends since they were both cast as Jamie and Claire Fraser in 2014 as they share the same humour and witty banter.
Despite their cheeky and playful friendship, Sam, 42, took to Twitter to share a sweet happy birthday message to his on-screen wife. He said: "Happy Birthday Balfe! Wishing you a fun (wet) day on set! (Perhaps the horses will give you another birthday gift…x)"
