This is what Katrina did on Ranbir's birthday

Bollywood heartthrob Ranbir Kapoor turned 32-year-old on Sunday and his girlfriend Katrina Kaif made it special by organising a surprise birthday bash. Katrina planned a surprise birthday party for Ranbir Kapoor with close friend Ayan Mukherji. It was a quite dinner at a five star in Mumbai with only Ranbir's close friend from the industry and childhood. Though, the party was also joined by Ranbir's next co-star Alia Bhatt. There are also reports that strict instructions were given to the hotel security that no photographers should be around the premises till the party goes on.
