Close friends say the role was cathartic as it gave her a chance to play out all the anguish and bitterness that she suffered when she was unceremoniously dumped by Ranbir Kapoor.

Says a source in the know, “Katrina was thinking of giving up her career, and setting up a home to have Ranbir’s children. Yes, that’s how serious she was in her relationship with him.”

Then, it all fell apart, Katrina’s world crashed when she was left stranded in the relationship.

According to sources, when she was offered the role of a deserted actress in Zero she saw it as an opportunity to heal her broken heart.

In the film, Katrina is shown as a nervous wreck after she is jilted by philanderer Abhay Deol.

“She dived into her own grief and hurt to play the role. This is why she seems so credible in this film. The tears are not faked,” says a source.
