Vidya Balan, who has been married to producer Siddharth Roy Kapur for almost four years, says she calls her husband Zampano, a character from the Italian film "La Strada".

Asked how has she saved husband Siddharth's name on her phone, Vidya said: "I keep changing the name for Siddharth in my phone. I don't keep names like Jaanu, baby, hubby and all."

The 'Parineeta' actress says she instead picks names from film's they've last seen.

"Invariably, I take names from films we've just last seen," Vidya said on a popular channel's show.

On being asked what was the last movie they saw together, Vidya said: "It was an Italian film named 'La Strada' and the character's name is 'Zampano', so temporarily that's how Siddharth name is saved and I keep teasing him Zampa..ano."

The National Award winning actress is gearing up for the release of her upcoming film 'Kahaani 2', the second instalment from the 'Kahaani' franchise. Directed by Sujoy Ghosh, 'Kahaani 2' also features Arjun Rampal and is set to release on December 2.
