Katrina Kaif looked pretty in a peach gown as she turned the bridesmaid for her sister.

Katrina Kaif left Mumbai for London at midnight on Saturday, to join her family for the wedding, rubbishing rumours and speculations that she was spending quality time with beau Ranbir Kapoor in Sri Lanka. Ranbir is shooting for Bombay velvet in the island nation.

"To insinuate that Katrina Kaif has nothing better to do than to follow Ranbir Kapoor around like a jobless star-wife wherever he is shooting is not just absurd but also insulting. Katrina Kaif didn't even have time to join her family in London in advance before the wedding. She left Mumbai for London just hours before the ceremony," said a friend of Katrina.

There were reports that Katrina was busy trousseau-shopping for Natacha.

"Rubbish!" says Katrina's friend.

"All her sisters as strong-willed and independent-minded as Katrina. Natacha did all her wedding shopping on her own. Katrina Kaif just flew in to attend the wedding. She flies back in a few days."
