Director Karan Johar, who walked the ramp here for his designer friend Rohit Bal at the Chivas Fashion Tour, says he prefers wearing ethnic sherwani than westerns on such occasions.

"I can't say I'm crazy about the idea of being a model. And please, it's not about modelling at all. It's about just lending my name to a friend who happens to be a dress designer. And this time it was a dear designer friend Rohit Bal who invited me to wear his couture, " Karan told.

"If I have to walk the ramp I prefer wearing ethnic to western. I've walked the ramp before. In fact the last time I did so was last year for the same fashion event, and it was again for a dear friend Nandita Mahtani. So you can say it's very hard for me to say no to friends. I guess it's better to walk the ramp than face the camera, " he added.

Karan, who was seen as an overweight guy in "Dilwale Dulhania Le Jayenge", is astonished at the amount of weight he has lost over the years.

"I can't believe I'm today seen to be slim enough to walk the ramp. I remember a time as a very fat child when I'd fool my mother into believing it's my friends' birthday.

I'd buy a one-pound cake, hide and eat the whole thing at one go. My turning point was when I saw my fat self on TV receiving the best director's award for 'Kuch Kuch Hota Hai', " said Karan.

As for directors rubbing shoulders with top actors and models, Karan said: "I'm flattered. And like I said I prefer walking the ramp. I hate acting. I never want to act."

As far as his role as producer and director is concerned -- Dharma Productions' next big release is Abhishek Bachchan, John Abraham and Priyanka Chopra starrer "Dostana". It is being directed by Tarun Mansukhani.

Apart from that Karan is gearing up to direct "My Name Is Khan" with Shah Rukh Khan.
