Controversial star Sanjay Dutt, who walked out of Yerwada Jail a few weeks back, looked surprisingly trim owing to his prison workout routine and now that he is gearing up for a comeback, Baba, as he is known, has started hitting the gym with a vengeance. The deadly Dutt recently uploaded a video of himself on Instagram, in which he is seen rigorously working out in a gym and we must say that the 56-year-old actor seems ready to give our younger actors a run for their money with his comeback film. Sanjay has also been sporting a quirky hairstyle and we wonder if he will carry this look in his comeback film, which will be directed by Sidharth Anand.
