There's so much fakeness in the fashion world, but Mum and Dad have always given us a good work ethic and were quite worried at first about whether I could make a living from acting. They've been together for 29 years and share the same values. I really do want to have that kind of marriage myself.

It's never fun having to bulk up for a job on an action film, then lose weight for another role. I don't actually mind working out, but it's the diet: I'm half-French, so I love my food, and boiled chicken breast for breakfast is not my idea of a good meal.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
