Bollywood actor R.Madhavan pulled a fast one on actress Swara Bhaskar on the sets of "Tanu Weds Manu" that released Friday.

The actor, along with the chief assistant director and Deepak Dobriyal, fooled the 25-year-old into believing that a woman who looked like choreographer Saroj Khan was actually Saroj.

A source narrated: "One day on the sets while getting ready to shoot a dance sequence, the cast was informed that legendary Indian dance choreographer Saroj Khan would be choreographing their dance steps. Swara was innocently excited and thrilled hearing this, being a huge Saroj Khan fan."

"Realising this, Madhavan came up with a scheme and introduced Swara to a woman who looked similar to Saroj-ji on the sets..., " said a source.

But once Swara realised that she was not talking to the real Saroj Khan, Madhavan burst out laughing, leaving Swara feel goofy and embarrassed.

Swara, who plays Kangana Ranaut's best friend in "Tanu Weds Manu", earlier featured in films like "Madholal Keep Walking" and "Niyati".
