Kareena Kapoor Khan

'Heroine' is about a declining and imbalanced superstar - a very brave and bold role. I wanted to test whether I could carry a role like this. I have given 200 per cent to this role. She's a very complex character, very aggressive, manipulative and bold, yet she's very fragile.

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.
