"So, a lot of people have been asking what Red Nose Day is about, and it seems the best place for reasons that are very hard to understand that the best place for me to answer this is in the bathtub," Robbie tells the camera in a pisstake of her scene from 'The Big Short'.
"It has everything to do with raising money and making people laugh, and it has absolutely nothing to do with bathtubs, shampoo, conditioner, soap, champagne, or nudity," she continues.
Robbie's been in a spoofing mood lately, tackling 'American Psycho' for Vogue and doing a bang up job of being absolutely terrifying.
