Vidya is a night bird! Before coming to any wrong conclusions we need to clarify that Vidya just loves shooting for schedules kept during the night time. "Vidya feels that a energy levels are high during the night rather than in the day. During the day the heat saps her making her energy levels go down. She likes shooting in the nights," said a close freind of the actress.Being energetic, Vidya has the units in splits. "She keeps the unit awake with her sense of humour. It keeps them hooked to work. Vidya is her chirpiest in the night," said the friend. Guess after Mr. Bachchan and Shahrukh Khan, Vidya is the next insomniac on the block!  -(SAMPURN)
