Ranbir Kapoor And Nargis Fakhri? What about Katrina Kaif?

Can it be true that Ranbir Kapoor is now going out with Nargis Fakhri , who also happens to star opposite him in his upcoming film Rockstar (2011) . Recently both where spotted coming out of a Mumbai multiplex with his friend Ayaan Mukherji. If this was a real date, then the Ranbit and Katrina pair did not last that long. For some time Katrina has suspected that Ranbir and Nargis were going out, and hence came to Delhi on the sets of thier film Rockstar.
