B-town price charming Ranbir Kapoor sure knows how to celebrate in great style!! News is that the 'Rockstar' gave a splendid surprise to his gorgeous co-star Nargis Fakhri at 20,000 feet up. It happened to be Nargis's birthday so Ranbir made elaborate plans to celebrate the occasion and arranged for a delicious cake and party for the flight, 20,000 feet up in the air!

Ranbir apparently per-ordered a scrumptious Ferrero Rocher chocolate cake from one of Mumbai's premium bakeries and quietly got it onto the flight without Nargis' knowledge.

An unsuspecting Nargis was sitting on her seat when suddenly one of her staff took her outside the cabin on some pretext. When she came back to the sitting area the entire team yelled, "Surprise!" and presented the chocolate cake filled with candles!

Ranbir, Mohit Chauhan, Producer Hiren Gandhi and all the passengers sang "Happy Birthday" while an overwhelmed and emotional Nargis cut the cake! She never expected anyone to even know it was her birthday that day! She then fed the cake to Ranbir and everyone present, after which entire crew partied on board the flight listening to 'Rockstar' songs with bonhomie all around.

Well, celebrating 20,000 feet up in the air with a sweet surprise by the charming Ranbir Kapoor is one birthday Nargis will never forget!
