Katrina has been roped in as the face of the Lux Purple Lotus & Cream, a soap infused with anti-ageing properties.
"I don't think every actress in Bollywood has been associated with Lux. A select few actresses, who they felt suited the brand right (have been associated with it) and they all have been actresses of great stature with wonderful careers and some wonderful work, " Katrina told over phone from Dubai Sunday evening.
"I am very honoured to join the group of people who have been with Lux over the years, " she added.
The new commercial has been shot in Bangkok and directed by Marco. While Katrina has been styled by fashion designer Rocky S for the ad, the music has been composed by trio Shankar Ehsaan Loy.
Actor Abhishek Bachchan also endorses Lux with wife Aishwarya.
