He will sport six-pack abs in Sajid Nadiadwala's 'Housefull 2'.
"The talented actor, who has previously in his career essayed serious characters for his films, will shed all inhibitions in 'Housefull 2' and will have his female fans drooling with his new look," sources close to the actor said.
They said the star is undergoing rigorous training to build an impressive six-pack abdomen for the film.
Director Sajid Khan said, "Rahul Khanna is an extremely handsome and talented boy. He just hasn't got the right break or role in a commercial film. 'Housefull 2' is will show the world that he has what it takes to be a star...including six pack abs."
Apart from Rahul, 'Housefull 2' will star Akshay Kumar, John Abraham, Rishi Kapoor, Randhir Kapoor, Asin, Jacqueline Fernandez and Mithun Chakraborty.
Meanwhile, Akshay will shoot his introductory scene in the film in Antarctica shirtless.
Getting back to his action space the introductory scene of the sequel to the comic riot will have Akshay Kumar fight villains in the freezing cold for a whole 10 minutes.
No other Bollywood film has been shot there before thanks to the climate and permissions, Sajid said.
"Antartica is the coldest place in the world. Only documentaries have been shot there. God willing, 'Housefull 2' will be the first feature to be shot," he added.
