Ranbir Kapoor and Deepika Padukone's chemistry is spoken about like something precious and rare like what Madhubala probably had with Dilip Kumar or what Raj Kapoor had with Nargis. It is so rare in B-town that fans were heartbroken when the pair who were actually dating each other, broke up and went separate ways. Their chemistry was like house on fire and it was heart breaking for everyone to see them part.
