According to an insider, things appear to be heating up between PC and Ranbir, "Both appear to have got over their break-up with their respective beaus -- Shahid and Deepika. Initially, Ranbir was reserved with Priyanka but over time, her fun and friendly nature broke his resistance down. They are even having little lovers' tiffs.
Says a source, "On Wednesday, Priyanka appeared to be having a heated conversation on the phone. She fell unconscious immediately after what everyone believes was a fight with Ranbir! Shooting was held up for three hours and resumed only after the actress felt a bit better."
Later that day, PC and Ranbir were to do a live TV for a news channel, and the production had booked a studio 15 minutes away from the hotel for that. They had both won awards and were to give bytes to the channel. While Priyanka turned up and gave her bytes Ranbir didn't. People on the sets were speculating if the fight between them was the cause."
Says Priyanka's spokesperson, "Priyanka is absolutely healthy and fine. There was fog in San Francisco for three hours and that's why the shooting was held up. It had nothing to do with her health. Producer Sajid Nadiadwala and Siddharth Anand remained unavailable for comment.
