They have gone to town talking about the new mature phase in their relationship- Deepika Padukone has even spoken of how Ranbir Kapoor might one day be the godfather of her kids- and they have worked together in one of the year's biggest hits, Ayan Mukerji's 'Yeh Jawaani Hai Deewani'.

 But the chemistry between Ranbir and Deepika was not just good acting in the film. Bollywood is still abuzz with news of how the former lovers got all cozy at a party hosted by co-producer of Yeh Jawaani..., Ronnie Screwvala, to celebrate the film's success. News is still filtering in from last week's bash at Screwvala's sprawling Breach Candy home where Ranbir, happy and high, grabbed Dippy for a lingering kiss in front of all the guests.

In a recent interview, Deepika has also spoken of a gift that Ranbir sent her after the film's success. Perhaps the new-found closeness between the two is just a result of propinquity—they have been spending a lot of time together, first shooting for Yeh Jawaani and then promoting it around the country, but the development has not gone down well with Ranbir's current girlfriend Katrina Kaif.
