Sanjay Dutt, who is currently serving his three and a half year term in Pune's Yerwada Jail, has turned 54 today.
Born to veteran actor Sunil Dutt and Nargis, Sanjay debuted as a child actor in Reshma Aur Shera in 1972.
Celebs like Ranbir Kapoor, Rajkumar Hirani and Bunty Walia have send birthday wishing letters to the actor fondly known as Sanju Baba.
Dutt's close friends have also addressed letters to him and sent them to his wife Maanyata before they were posted to him.
Meanwhile, the actor could not meet his family members on his special day as visits are restricted to once a month and their next meet is due in August.
