Ranbir Kapoor, Nargis Fakhri's rumoured affair comes to an end?

What went wrong between the rumoured couple Ranbir Kapoor and Nargis Fakhri? Recently in a party at Grand Hyatt, Ranbir and Nargis avoided each other by hardly speaking to each other. Reportedly throughout the evening Ranbir and Nargis were in separate sections of the party.

Sources informed a leading newspaper, "Nargis and Ranbir hardly spoke to one another. This was an important evening for Nargis, as it was her first appearance independent of the Rockstar events. And she made it clear that she was there at the party to meet the who's who of the entertainment industry, something that she had not been allowed to do during the shooting and publicity of Rockstar."

In fact shockingly Nargis got along really well with Ranbir's ex-girlfriend Deepika Padukone in the party, then what have actually gone wrong between the Rockstar actors?
