Mumbai, Aug 26 (IANS): Katrina Kaif's sister Natacha tied the knot Sunday and thanks to the Bollywood actress' busy schedule, she could only leave Mumbai for London just hours before the ceremony.

Katrina left Mumbai for London midnight Saturday to join her family for the wedding, thereby rubbishing all the rumours and speculation regarding her alleged time-off for a visit to join Ranbir Kapoor in Sri Lanka.

A friend of Katrina said: "To insinuate that Katrina 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 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."

That also shoots down other speculation 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 just flew in to attend the wedding. She flies back in a few days."

Among Katrina's forthcoming films are "Dhoom 3" and "Bang Bang".
