As part of the latest secret task, the actor had to walk a show pony through the house without Bianca Gascoigne seeing him.

It obviously brought back memories of appearing in GoT as Jeor Mormont as he bellowed "I am the Lord Commander, and this is my steed" while completing the task.

It delighted fans.

He even compared the horse to his housemates, saying in the Diary Room: "It's going to be wonderful to share a brief time with something whose IQ is probably greater than some of the people in here."
