The film in which Sidharth Malhotra is currently working on requires him to look lean for his boy next- door character. But the next project needs the actor to bulk up for a tough look.
An insider says, ''Once he finishes shooting for his current project, he will have to start working on his body again and gain at least 10 kgs. It's quite a challenge but Sidharth is ready for all the action.''
Looks like the actor will have to spend a few hours more at the gym now.
