Vidya Balan tells MiD DAY in an exclusive on her recent visit to town to promote her forthcoming film The Dirty Picture

But Vidya Balan the person thankfully remains the same. She still greets you with a disarming smile and speaks with characteristic patience despite catching only four hours of sleep a day in her final leg of promotions.

Perched atop a chair, Vidya nods to the recent Godzilla - Kolaveri Di, her eyes fixed on the video of the song on her phone. "Too cute," she says even as her make-up man adds a jot of fuschia to her eyelids.

The interview happens while the colour of her nails changes from a fiery red to a daring purple aiding her matamorphosis from Vidya to Silk (her character in Silk Smitha) for the press appearance. She's a chameleon. A loveable one. Excerpts from the interview.u00a0u00a0u00a0u00a0u00a0u00a0u00a0u00a0u00a0
