Bollywood's light eyed actress Rani Mukerji has managed to keep her relationship with Yash Raj's head honcho producer Aditya Chopra a secret for years now. But now it seems that the couple is slowly and steadily opening up about their relationship and are comfortable in coming out with their equation in open. 

The actress who a few days back was spotted at Mumbai's international airport with Aditya Chopra at distance recently flew to spend her birthday with the Chopras in London. It is heard that Rani and Aditya were accompanied by Yash Chopra and Shah Rukh Khan for a quite dinner.

The father-son duo is currently shooting for their forthcoming magnumopus love story starring Shah Rukh Khan and Katrina Kaif in London. Rani being very thoughtful of their packed schedule decided to fly there to bring in her birthday celebration last week.
