While Ranbir made headlines again for being in New York with his ladylove Katrina, the actor in fact made the trip educative.

After his short holiday with his beau, we hear that he enrolled for a crash course on stammering, at one of the leading schools there. And why? Well, the actor is seriously preparing for a role in an upcoming film, where his character is a person who stammers. Wow! This kind of dedication is very rare amongst today's young actors.

While Ranbir knocked it off playing dumb in Barfi, this role sounds pretty more challenging for him. And no second thoughts, he sure will pull off the role with class.
