Sophie Turner slapped Conan O’Brien hard as she taught him a drinking game on his show Wednesday.

Turner, who has been busy promoting her latest flick “X-Men: Dark Phoenix”, insisted: “I really want to play this game with you,” — a game called Tequila Slaps.

The actress told the host, “Two people stand opposite one another. One person takes a shot and before they have time to swallow it, the other person slaps them around the face.”

As O’Brien downed his shot, Turner whacked him across the face, to which the host said: “Wow, that was a fantastic slap!”

The “Game of Thrones” favourite then took her own shot, explaining how she had to get on a flight after the interview so would like to be drunk.

She also recalled how she’d appeared on O’Brien’s show before with a purple hand-slap impression on her face from playing the game.
