Deepika Padukone is one of Bollywood’s busiest actresses today. Currently the actress is working in four films simultaneously, besides the one being directed by Sanjay Leela Bhansali, which has Ranveer Singh in the lead. Known to be a perfectionist, Bhansali has set up a workshop to train the lead pair on various techniques that reportedly takes up 15 to 18 hours a day. Grapevine has it that Deepika and Ranveer started dating while spending considerable time for their workshops.
