In this case, after all these years, a dance master has revealed an interesting incident about her. During the shooting of 'Brothers' in 2011 at Sweden, a shot was taken where Kajal should dance on a rock surrounded by waters. She also has to wear Saree for that sequence.
Initially, she was asked to do it near the shore and they planned to take it as a long shot. But Kajal Aggarwal did it without any hesitation and she completed the dance in a single shot. You can take a look at those photos above. No wonder, she is still the topmost actress!
