Folks... who can say no to Salman.. Katrina couldn,t resist the power of Salman the 'Tiger',  cutting short her  vacation the lass flew to Mumbai to join him for the launch of the song 'Masha Allah' from their highly awaited 'Ek Tha Tiger' produced by India's premium production banner Yash Raj and helmed by Kabeer Khan.

The song which was launched day before is rapidly spreading like an epidemic all around and was initially scheduled to be launched next week... but with the Ramzan period nearing Salman wanted the song to come out for his loyal fans before the fasting month so the Thursday launched was planned..

Katrina had her diary full as after the shooting for Ek Tha Tiger wrapped up a couple of weeks ago, Salman started work on Dabangg 2 and the London beauty in her Bollywood duty Katrina flew to her mother land London to shoot the next film with Yash Chopra. After the film's schedule wrapped up, Katrina wanted to stay back in London and spend time with her family.

A close hand reveals, "The location was quite far from where she lives and since she didn't want to disrupt the shooting schedule, she was living in the hotel the crew had put her up in.

Only once the schedule had wrapped up, she decided to spend some time with family. But she was happy to cut short her vacation when she realised that the song was getting launched earlier on and she wanted to be there for the launch of their first song together."

Katrina flew in to Mumbai a day before the launch. And we all know what happened later..

How sweet and loving of you dear Katrina..
