Ranbir Kapoor who's shooting with Priyanka Chopra in New York, just can't stop teasing his co-star goodnaturedly about her National award.According to members of the unit, since the announcement reached the US last week Ranbir keeps mock-complaining, “Damn! Now you're the second National award winning actress I'm working with (after Kokona Sen Sharma in Wake Up, Sid). I better buck up.”
