It's actor Shahid Kapoor's wife Mira Rajput Kapoor's birthday today and to make the occasion special, he penned a loved-up post on Instagram.

Calling Mira the centre of his world, Shahid wrote, "Not just to share your joys but to share your sorrows too. Not just for every day we smile in each other's arms but on the days we cry in each other's arms. You are the centre of my world. And I wouldn't want it any other way. Happy happy birthday."
