I think if more girls followed your courage and lust for life we would land up with a bunch of very happy, strong, brave and fulfilled girls. So let's call this Bebo day and use it just for that. A day dedicated to following your heart and gut! Love you bro!"

Happy birthday to you @kareenakapoorkhan."
