Bollywood superstar Aamir Khan, who recently celebrated his birthday in Mumbai, once spoke about how he learnt tap dancing for `Dhoom 3`. A BTS video shared by the actor`s production house, shows the actor breaking down the process of learning the dance form. While tap dancing may take a few years to get the basics clear, Aamir was given the window of 45 days to not just learn but ace the dance form.

The actor said in the video, "I have always been fond of tap dancing. How fast they move their toes and their heels to make a certain sound pattern and all that. Aditya Chopra was thinking of modern tap dancing which is stomping. We had to do a title song in `Dhoom 3` and everyone was discussing what type of song it would be. So I told Adi that I have always been fond of tap dancing. He got very excited. He said yes, tap dancing. There has never been tap dancing in Hindi films. I said, I will learn."
