However, the highlight of the party was Ranbir's mommy Neetu Kapoor bonding in a big way with his Rockstar co-star Nargis Fakhri.
For all those who do not know ... it is being rumoured that Ranbir and Nargis are more than just good friends. In fact, the two are even reported to be dating each other.
If sources are to be believed, while Neetu Kapoor was cordial with Deepika and Priyanka, it was Nargis who was showered with Neetu's affection. Mommy dear apparently hung with Nargis till the end, making sure that she was comfortable and at home. Hmmm....what's cooking?
As for Deepika Padukone, she exchanged a few hellos with RK and later hung on with director Ayan Mukherji all night.
Ranbir Kapoor celebrated his birthday yesterday in style, even holding a birthday bash for all his friends and family. The party was attended by all the big wigs of the industry including Ranbir's former love interests Priyanka Chopra and Deepika Padukone.
