Talking about her upcoming film 'Jersey', Mrunal Thakur said that she was nervous while filming a slap scene with actor Shahid Kapoor. "I was very scared...I was tense... [and thought] I shouldn't overdo the output. But Shahid helped me...by egging me on, [he said] 'tu maar mujhe'." Shahid and Mrunal are coming together for a film for the first time.
