New Delhi: After creating waves as Lolita and 'B'idya Bagchi, Vidya is back in Kolkata, but not for a movie this time. The stunning actress was seen shooting for a new Horlicks commercial with children in Kolkata a few days ago. Set around the backdrop of nutrition, the new campaign is not for any specific product from the brand and is the first of its kind for Vidya Balan. Vidya has already shot for the latest campaign of Horlicks and if our source is to be believed, she had a great time shooting. Vidya says, "It is always a treat to come back here as Kolkata is like second home to me; I fall in love with this city every time I come here."
