Katrina Kaif to have an extended birthday celebration in London?

After a low-key party with close friends here, Katrina Kaif jetted off to London on the night of her 32nd birthday along with beau Ranbir Kapoor for an extended celebration. Sources say the actress wrapped up her brand commitments just in time to usher in her big day (Thursday) and spent the afternoon with her industry pals in Alibaug before taking off to the UK.

"Katrina and Ranbir took a British Airways flight to London at 1.50am on Thursday. They will be there for a week. It was an impromptu decision to fly out of the country; she was so tied up with different shoots that she thought she would have a working birthday. But before leaving, she had a quiet dinner with five or six close friends since she is not a big believer in the idea of elaborate birthday parties," says a source close to the actress.

While Kat's sisters are in London, her mother is said to be in south India where she supports a charitable organisation.

"They might meet her sisters there, but the actual reason behind this getaway is to spend quality time with each other. In any case, she visits her family once a year on Christmas," adds the source.
