Olivia Colman swore when she met Queen Elizabeth in real life at a film event at Windsor Castle six years ago.
The Academy-Award winner, who plays the monarch in the Netflix series The Crown, said she was attending a film party at the castle when a man starting herding guests together.
"I didn't think she'd be there and suddenly we all ended up in a big queue. I thought somebody was using the rooms for the bash and then suddenly we looked down the corridor and went, 'Oh fuck'," Olivia told The Mirror.
The man then told the guests in the queue to just do a little bow and to keep moving.
