Vidya Balan was in for a pleasant surprise when her producer hubby Siddharth Roy Kapur paid her a visit at a suburban studio in Mumbai during the promotions of her next film, 'Humari Adhuri Kahani'.

Siddharth, who was visiting the sets of his production 'Fitoor', decided to surprise her over lunch, given that she is busy and will be travelling for the next few days. Wonder what they tucked into?
