The 33 year-old has won two Olivier awards and a golden globe for her performance in The Affair - yet she still can't seem to accept she's an incredible actress!
After her performance in Constellations, she has been rumoured to be dating co-star Jake Gyllenhaal, following TONNES of on-screen chemistry.
Ruth believes that when you act, you are being more truthful, more open and more honest than you would be in the same situation in reality.
She is fast becoming a household name in the US thanks to her role in The Affair and is currently promoting the show's second series.
The show hasn't aired yet in the UK and Ruth believes it might be because it's too racy for Brits - cheeky!
As a very modest actor that hasn't quite realised her talents, despite her popularity, she describes herself as 'quite straight, quite zen and not particularly dramatic' - sounds like our type of girl!
We're hoping we get to see a lot more of her as she lines up to take on more films once she finishes filming season 2 of The Affair.
