It's not my sister Isabella in that raunchy video:

Katrina Kaif has set a new trend– she's merging business with a social cause and we are impressed!

Katrina's brands have been doing exceptionally well after having Katrina on board and are now passing on the goodwill to her mother's charity that work with unwanted and abandoned baby girls.

Reveals a source, "Katrina Kaif is the first Bollywood star to initiate brands into tying up with charitable trusts- in fact a certain diamond brand in question has just tied up with Katrina's mother Susanna's charitable organization Relief Projects India."

We come to hear that this donation is an approximate 50 lakhs and many of Katrina's other brands are also contemplating such tie-ups.

So do we hear her contemporaries chasing to follow suit?

Katrina Kaif will soon be seen next in Farah Khan's 'Tees Maar Khan' alongside Bollywood Box office King Akshay Kumar. Talking about her co-star Katrina says, "He's my comfort zone, working with the same actor time and again doesn't provide any challenges, but with Akshay in the same frame, I am more at ease with my performance."

Talking about her sister Isabella's name being dragged to the raunchy video episode, Kat says, "The video has been circulating for the last six months and it's absolutely fake! "

"My mom is freaking out over certain stories appearing in the papers and is planning to legal action. Even YouTube knows it's a fake video and that it's not Isabella.

I request people not to harm a minor (Isabella is 17 years old) by carrying these fake videos. Do you think this video would be floating around for so many months if it was true?" she adds.
