Aamir flew to Australia to learn the dance from Dein who had choreographed the Sydney Olympics opening act and 'Happy Feet 2'.
The actor spent a while in Australia and learnt the dance form with the choreographer's students, mostly in the age group of 10 - 24 years. Aamir had to learn the 'grungy tap' dance which is high on energy and more difficult than the classic tap dance.
"Aamir had visited Dein Perry's academy in Australia to learn the grungy tap dance. After the training was done, the dance team came to India to shoot the song," a 'Dhoom 3' spokesperson said.
Releasing on December 20, 'Dhoom 3' is directed by Vijay Krishna Acharya and produced by Aditya Chopra.
