"He has always shown faith in me. He will tell me what he has in mind, and then leave it. But he is very demanding. If he doesn't like the feel of the sets, we know that he will never be happy shooting in it."

And they have had their share of creative differences.

"We had a huge set for the song, Bole Churiya, in Kabhi Khushi Kabhie Gham. Karan came after the first coat of paint was applied on the sets. Usually, we put two-three shades of colour to build the final colour. He took one look at the walls and exclaimed, 'I don't want a strawberry cake!' I had to convince him that it wouldn't look like a strawberry cake after the work was done. But at that point, it was very difficult for him to visualise what the result would look like. If I hadn't worked with him all those years, I may have got flustered and scared," she says.

The art director knows Karan so well she designed KANK without going much on the sets. "I controlled the sets from home. But he didn't mind that. He was very understanding," she says.

"Another time, I was late on the sets of his television show, Koffee With Karan, and he was throwing tantrums all over. He didn't like the stairs on the sets. It was a new group working with him, and they didn't know how to deal with him," she explains. "I think he just needs his team around him."
