Filmstars makes the best brand ambassadors or so it seems. We have Shah Rukh Khan endorsing Omega, Fardeen Khan is currently the Provogue man, Madhuri Dixit was signed on by `Emami` and now there`ll be one more pretty face to launch a product.

The Khanna girl has been added to the long list of celebrity endorsing brands. Swiss`s top watchmaker Mavoda has signed Twinkle Khanna as their brand ambassador. Someone sure is making good use of their `time.`
