According to the news "
Farah Khan" is "
Hrithik Roshan's" dance guru OR Trainer because of the Hrithik Roshan debut film "
Kaho Naa Pyaar Hai", is a choreographer by "Farah Khan". BUT I'm not fully sure about that maybe he learned to dance from out of India too.
Actually, Farah Khan is the most popular dance choreographer in India Bollywood and other entertainment industries and she hosted lots of reality show & dance reality shows.
