Here's what Amitabh Bachchan wrote for Abhishek:
In his blog, Mr Bachchan, 74, shared a few images of the father and son and wrote: "He, my son, Abhishek turns 41 .. and I cannot imagine the time passed .. those hours at the Breach Candy Hospital where Jaya struggled with her labor .. and that OPT door opening and Dr Shah, our family doctor, poking his head out of the door and asking - 'what did you want ..?' .. and his anticipated smile giving away that a son had been born .. the champagne bottle opened, the nurse and sisters on duty were given a sip each much against their wishes and protocol, but .. there it was .. excitement .. and the joys of another addition to the family .." (sic)
Abhishek made his Bollywood debut in 2000 with J P Dutta's Refugee also featuring Kareena Kapoor. He gave his first commercial hit in 2004 with Dhoom.
Abhishek married Aishwarya Rai Bachchan, his co-star from Dhai Akhsar Prem Ke and Guru in 2007. The couple's first child, a daughter, whom they have named Aaradhya was born in November 2011.
A die-hard football fan, Abhishek co-owns football team Chennaiyin FC in the Indian Super League (ISL) and actively promotes the game.
