When I want to make people laugh - Sushmita Sen

Former beauty queen Sushmita Sen, who teams up for the fourth time with David Dhawan for forthcoming comedy "Do Knot Disturb", says she never thinks twice before saying yes to the maker of comedies.

"I enjoy doing comedy and David Dhawan is the one who brought me into it with 'Biwi No.1'. So every time I want to laugh and make people laugh, it is with him.

He is always there for me so I end up doing the same," Sushmita told IANS over phone from Mumbai.

"The thing is that since he and Vashu Bhagnani (producer) both gave me 'Biwi No.1', I have pretty much gone with his guts. When he asks me for a film, I just do it. We usually don't get down into the role or anything," she said.

The 33-year-old has earlier given three laugh-riots with Dhawan - "Biwi No.1" (1999), "Kyo Kii...Main Jhuth Nahin Bolta" (2001) and "Maine Pyaar Kyun Kiya" (2005).

"Do Knot Disturb", a co-production by BIG Pictures and Vashu Bhagnani, is a comedy on marriage and also stars comic hero Govinda, Lara Dutta, Riteish Deshmukh and Ranvir Shorey. Sushmita was excited about not only working with Dhawan and Bhagnani but also teaming up again with Govinda, in "Do Knot Disturb", which releases Oct 2.

"Whenever I get to work with this family of three, I just say 'let's do it now'. Working with them is a fantastic experience. We have formed such a relationship that there is a comfort level and I know David as a director so well that I know exactly what he wants," the actress said.

"So there is no work stress. He works in great detail...you know your scene, his style of shooting...He shoots the film at a certain pace," she explained. "Vashu-ji, on the other hand, is a fantastic producer. He doesn't leave any stone unturned to make or promote his films. And it's just a lovely chemistry working with Govinda," she said.

So what character does she play in the comedy on marriage? "I play Chichi's (as Govinda is fondly called) wife yet again (after 'Kyo Kii... Main Jhuth Nahin Bolta') but this is a very 21st Century wife and has her takes on marriage and infidelity."

Not many know that the Bengali beauty was asked to put on 14 kg for her character in the movie. "I was asked to put on 14 kg but I told Vashu-ji and David 'I don't think it'll be easy for me to lose that much; so let's not attempt putting it on'," she said.

"Finally I put on nine kilos, but then I had a month and a half to lose it, as I had to go back and shoot for 'Dulha Mil Gaya' after that," she added. Losing the extra flab wasn't an easy task for Sushmita, who now sports a toned frame.

"It was definitely a difficult task, as it required a lot of discipline. I had to stick to two-hourly eating and had to manage a workout regime. I had a very good trainer, Mupur Shikhare, and a wonderful dietician, Pooja Makhija; so these guys handled it for me and I was back on track," she said. Sushmita also shrugged off rumours that Riteish was the main lead of the film. "This is very much a Govinda film," she said.
