Ranbir Kapoor planned a special birthday surprise for his Rockstar co-star Nargis Fakhri up in the air when the duo was flying to Nagpur for the promotion of their movie. Ranbir, Nargis, singer Mohit Chauhan and producer Hiren Gandhi were on board on the charter flight when Ranbir brought
out a cake for the lady on Thursday.

The actor had pre-ordered a Ferrero Rocher chocolate cake from one of Mumbai's premium bakeries and quietly got it onto the flight without Nargis's knowledge, said a source. While Nargis was sitting on her seat unaware, one of her staff members took her outside the cabin on some pretext. When she got back, the entire team yelled "Surprise", and presented the cake to her. The team sang "Happy Birthday" for her, while an overwhelmed and emotional Nargis cut the cake.

The debutante, who turned 32 on Thursday, fed the cake to Ranbir and others. All of them partied on the flight listening to Rockstar songs, which have become a rage. Rockstar, directed by Imtiaz Ali, is produced by Shree Ashtavinayak Cine Vision Ltd and Eros International. It will release on November 11.
