Imran Khan has paid a tribute to Bollywood’s three Khans – Aamir, Salman and Shah Rukh – in the title song of his upcoming film ’Mere Brother Ki Dulhan’ by copying steps from their popular songs ’Paathshaala’, ’Munni Badnaam Hui’ and ’Chhaiyan chhaiyan’, respectively.Imran, who stars in the Yash Raj Films film opposite Katrina Kaif, shot for the peppy song in Mumbai, New Delhi and Dehradun. In the song, Imran goes searching for the ideal bride for his brother. He dances at an airport, mimicking his uncle, Aamir, by performing the same steps that the latter did in the song ’Paathshaala’ in ’Rang De Basanti’. On the road, he copies Salman’s famous steps from the blockbuster ’Dabangg’, and he has also shot atop a train a la Shah Rukh’s ’Chhaiyan chhaiyan’ from ’Dil Se’. He may not be a great dancer, but the 28-year-old has managed to copy the three Khans quite well. ’Mere Brother Ki Dulhan’ also stars Pakistani actor-musician Ali Zafar. The romantic comedy will release September 9.
