Vidya Balan, who is essaying the role of late south Indian sex bomb Silk Smitha, might have shed all her inhibitions in front of ‘The Dirty Picture’ cast and crew but there is someone, who does make her feel extremely conscious. The actress was shooting yet another steamy scene when to her horror she saw her father paying her a surprise visit. Papa Balan had visited the sets to see if Vidya was feeling fine, post hospitalisation following exhaustion and stress. On realising Vidya wasn’t too comfortable emoting sensual scenes in his presence, the sweet dad left the sets.
