Margot Robbie turned up on 'The Tonight Show starring Jimmy Fallon' to answer some secret questions, and down some shots.

Fallon's 'Loaded Questions' involves he and his guest reading a question to themselves, saying the answer, and choosing whether or not to reveal the question. If they don't reveal the question, they must take a shot - hence the term "loaded". Harley Quinn herself, Margot Robbie, is this week's guest to take part in the drinking game.

We won't ruin it for you, but the game is quite revealing, as you'll be able to see below.

Jimmy Fallon also recounts quite a sweet story about the time that he and Kate Hudson hung out in Central Park to go ice-skating together, back when they both starred in 'Almost Famous.'

Margot Robbie, the slippery little divil, we REALLY want to know the question to your "Will Smith" answer. Please, even just a hint?
