Superstar Kamal Haasan turned 70 on Thursday and his actress daughter Shruti Haasan penned a heartfelt note for her “appa”, whom she said is a “rare diamond”. 

Shruti took to Instagram, where she posted a picture of her and her father in the gym. In the image, Kamal is seen dressed in athleisure while the actress could be seen all dolled up. Their faces cannot be seen as their backs are towards the camera.
