Yash Raj Films (YRF) is going all out to ensure that 2013 ends on a high note. The 'Dhoom 3' team has spent a whopping Rs 5 crore on its title track.

The song not only features Aamir Khan and Katrina Kaif, but also 200 professional gymnasts, who were flown in from the US. Obviously, the cost of hiring the professional dancers was also included in the over-the-top budget.

The dancers gyrated to the song's beats on a specially-made set that took about two months to prepare.

This song is yet to be released but has already made headlines. Fans are waiting with baited breath to give their verdict on the song as well as the film, which is clearly the much-awaited one of 2013.

The title track of 'Dhoom 3' will most likely go down in history as one of the most expensive song.
