Shefali Chhaya of 'Monsoon Wedding' and 'Satya' fame exposed her hubby Vipul Shah as a serious director. "He can be quite a prankster on the sets. In fact, one day he has shooting and suddenly asked the designer to interchange the clothes of his two heroines at a day's notice, claming that their roles had been interchange. The designer went batty trying to fit the shorter actress' clothes to the taller one and all the while the entire unit was in splits. You should have seen the relief on the designer's face once the truth was revealed!", Shefali reveals.
