New behind-the-scenes pictures from the production set of “The Last Kingdom” Season 4 have “leaked” online. The hilarious posts on social media show the cast members having fun while enjoying a break in between filming their scenes.

Lead cast member Alexander Dreymon, who will be reprising his role as Uhtred, shared a picture of him with fellow cast member Mark Rowley on his Instagram page recently. “EXCLUSIVE: Uhtred and Finan’s secret honeymoon pictures leaked,” Dreymon wrote in the post that shows the two actors embracing while enjoying a beautiful view.

In another post, Dreymon sang for his fellow cast member Millie Brady, who will be reprising her role as Aethelflaed. Brady tried to listen to the song patiently, a song about how the actor can’t live without her. The actress couldn’t contain her laughter when Aldhelm actor James Northcote joined in by singing “me too.” Dreymon stopped and turned away with some mock-anger at Northcote.

Aethelflaed is married to Aethelred (Toby Regbo), but it can hardly be described as a happy marriage. It remains to be seen if she will develop a romantic relationship with Uhtred in “The Last Kingdom” Season 4.

Dreymon called Northcote a “3rd wheel” in his post. In the TV series too, Aldhelm confessed that he has feelings for Aethelflaed, a storyline that may play out on the show if he survives.

Aldhelm’s fate is unknown in Season 4 as of this writing. It remains to be seen if the character will recover from his wound or if the audience will see him as a corpse. The character’s love for Aethelflaed may be a good reason for his return.

The cast members are having a lot of fun filming “The Last Kingdom” Season 4. A video on the official Instagram page of the TV series shows Dreymon and Sihtric actor Arnas Fedaravicius “horsing around on set.”
