Michael Flatley has a lot to answer for.

She may be all proper and poised as Queen Elizabeth II on Netflix's 'The Crown' but Claire Foy, thankfully, is much more down-to-earth, relatable and flawed in real life.

Foy sat down with W Magazine to talk about everything from how she got her role in The Crown, what it was like to go back to work after having a baby, and why she has a celebrity crush on Mark Ruffalo to her Irish heritage that resulted in a childhood encounter with Riverdance that has left her mortified ever since.

And we can't really blame her.
