When Sophie danced in a 10 kg costume

Singer-actress Sophie Chaudhary's item number with Sanjay Dutt in "Kidnap" not only required her to look sensuous, she also had to wear a costume that weighed over 10 kg.

"Sophie wears two different costumes in the song. While the one with mirrors weighed over five kilograms, the other one, made out of crystals, weighed over 10 kg," designer Shilpa Bhatia said.

"The unit members including me were amazed at Sophie's enthusiasm. She didn't let the costume weigh down on her or her charged spirit," said Bhatia.

"The funniest part was when Sophie would change into her regular clothes, she used to tell everybody around that she felt so much lighter and used to start talking about weight loss. Just removing that heavy costume used to make her feel lighter," she said.
