Ranbir’s surprise birthday party turned out to be quite an extravagant affair. While ex-girlfriends Deepika Padukone and Priyanka Chopra turned up to be a part of the celebrations, the birthday boy’s current chick and Rockstar co-star Nargis Fakhri was seen bonding big time with his mother Neetu Singh. The two were spotted hugging each other and sharing pleasantries. Looks like this time Ranbir will get a green signal from mommy dear for going ahead with his lady love. But will Casanova Ranbir be able to stick to this new relationship for long or it will turn out to be yet another short-lived love story , we wonder, sigh!
