Katrina Kaif has been signed up to endorse Lux Purple Lotus and Cream, a new range of anti-ageing soap which is supposed to have the essence of the purple lotus.

And no, she has not replaced Aishwarya Rai Bachchan, as the former Miss World endorses a different range of the same brand.

Katrina recently spent four days in Bangkok shooting for the 30-seconds-long advertisement.

In the ad, the lissome lass enters a late-night party and accidentally touches a hot guy.

The guy is (naturally) impressed with the smoothness of her skin and sparks fly between the two.

The advertisement for the new campaign went on air on Monday.
