Farah Khan's upcoming film "Happy New Year" starring Shah Rukh Khan and Deepika Padukone, has already created tremendous buzz among the public with its recently released trailer and promotional SLAM tour that will start soon.

In fact, the film's first song "Indiawaale" is expected to launch on Wednesday (3 September).

It has to be remembered that the makers have left no stone unturned to promote the film. 

Interestingly, Bachchan will reportedly go shirtless during the promotional tour. This would be the first time that the "Dhoom" series actor, who is not a fitness freak, will be flaunting his bare body. In fact, for the past few months, the actor is sticking to a strict diet and work-out regime to get into proper shape.

"It was kind of a dare that he (Abhishek) accepted from Shah Rukh on the sets of Happy New Year. This was after several portions of the film were already shot. Shah Rukh told Abhishek that if he lost those extra kilos, he would allow him to go shirtless on the world tour." a source close to the film's team told Bollywood Life. 

While the entire team of "Happy New Year" is all geared up for the tour, Bachchan is working hard to sweat out the extra kilos to have his shirtless moment on the tour.

"Abhishek has been very sincere about his training. He has also altered his diet. His co-star Sonu Sood has also given him a lot of inputs regarding his workout regime. A friend of the actor has confirmed that he has lost around 7-9 kg thanks to the strict regime. Looks like Abhishek is leaving no stone unturned to flaunt a shirtless body."

The promotional tour that will start in September, will include a series of concerts across various cities in the US and Canada. Apart from Bachchan, Shah Rukh and Padukone, other stars of the movie will also be accompanying them, including Sonu Sood, Boman Irani, Malaika Arora Khan, yo Yo Honey Singh, director Farah and singer Kanika Kapoor of "Baby Doll" fame.

"Happy New Year" is slated to release worldwide on 23 October.
