Actor Imran Khan, who is currently busy promoting his forthcoming film "Ek Main Aur Ekk Tu", was in for a surprise when he was greeted by a flash mob during his visit to New York University.

As many as 100 students from the university and other neighbouring colleges broke into a dance on popular songs "Ek Main Aur Ekk Tu" and "Auntyji" from the movie.

"I had a blast at NYU. Everyone was so enthusiastic, they put on a very polished, confident show, and the surprise flash mob at the end was perfectly executed. My best wishes to all the students involved," Imran said in a statement.

The students had been practising for the performance for over two weeks, ahead of Imran's visit to New York as part of the promotional tour.

"As the president of NYU Dillagi, a Bollywood dance team, I knew we had to have simpler steps that the general public would be able to do and we sent videos out to the public. I thought that the flash mob came out even better than expected since people kept joining the mob throughout the sequence and it definitely surprised those that did not know of it ahead of time," Mohit Chhatpar, coordinator of the flash mob, said.

"It was really fun to be doing a flash mob and having Imran among us was all the more fun. He was very sporting and interacted with the students. We are excited about this movie as well and are glad he could come and be among us to talk about his movie," he added.

The Dharma Productions' film, also starring Kareena Kapoor, is set to hit theatres Feb 10.
