Katrina Kaif, these days is busy with the promotion of her forthcoming film 'Raajneeti' in which she will be seen in a de- glam look.

Now the news is that this sexy actress also has her best friend accompanying her where ever she goes. And well her best friend is none other than- Diamonds!

A friend of Katrina said, "Katrina feels that diamonds are a symbol of security that you can pass on to the next generation. And that is why they are so special to every woman. She firmly believes that diamonds are a women's best friend."

Apart from promoting her latest film, Katrina is also busy clarifying about the sex tape, allegedly of her younger sister Isabel Kaif. Katrina appealed to everyone that they shouldn't believe in such fraudulent claims.

Well we can understand the concerns of sis Katrina toward Isabel, who by the way is making headlines for all the wrong reason even before entering B-town.
