Kangana Ranaut is upbeat about her super girl role in Rakesh Roshan’s Krrish 3 alongside Hrithik Roshan. Admitting that the role is crucial for her career, Kangana says, “I had to push my other films ahead. The Tanu Weds Manu sequel required me to gain some weight, which I can’t do right now because I had to lose four kilos for Krissh 3.” She adds, “I am sculpting my body to fit into a special skin-tight costume. The whole training is taking so much of my energy that I’m automatically losing weight. The somersaults and kicks are new for my body, so there’s muscle pain all the time. I will also be jumping from heights, plus I’m learning karate and kickboxing.” The actor, who claims to be the first choice for the role, was called back after Chitrangda Singh and Jacqueline Fernandes walked out citing date issues. She will commence shooting for the Ishqiya sequel around June and will continue shooting for Krrish 3 till October.
