The 28-year-old Sri Lankan beauty has to look like a college girl in the film and she said: "During 'Race 2', I had to lean down completely because there was a lot of action scenes in it. For this film, I was asked to gain weight as I am playing a college girl."
"I could not afford to have the perfect zero size body. I was 51 and now I am 56 for 'Kick' and I am very happy with my body," she added.
When asked if this brings any pressure on her, she said: "There was a lot of pressure, but my main concern was not to disappoint Sajid Nadiadwala. He must have seen something in me that he offered me the film. When he showed confidence in me, I didn't want to disappoint him."
"Kick" is important for producer Nadiadwala too as he embarks on a new journey with the action drama - it marks his debut as a director.
Jacqueline praises Salman's "helping nature".
"He is not the kind of a person who will leave you mid way. It's a pleasure to work with him," she added.
