Imran Khan has been pumping iron for his role in an upcoming sequel could be to look right for his part opposite Sonakshi Sinha

Imran Khan has been busy working out hard in the gym for his role in the sequel of Once Upon A Time In Mumbaai.

Word is that it is not to compete with co-star Akshay Kumar in the brawns department; instead it appears that the actor is going all out to make sure he looks absolutely physically compatible opposite his on screen ladylove Sonakshi Sinha.

While Imran has a rather skinny frame, Sonakshi is known for her curvy and slightly broad figure. We overheard the actor telling a friend, "I am getting into bodybuilding, so that I can be seen in the frame with Sonakshi."

Imran has two months to prepare for his role, as the shooting of the film begins in August.

Sonakshi's weight issues have been part of dining table conversation ever since her debut with Salman Khan in Dabangg. Also, after working with senior actors like Sallu and Akki, finally Sona is now doing films opposite actors from her own age group.
