Bollywood star Mallika Sherawat currently riding on the crest of glory, has been delivered a piece of bad news. Industry's oldest body of producers, the Indian Motion Picture Producers' Association or IMPPA asked her to return Rs 2.5 million to Studio 18. Following a complaint by Studio 18 against her "starry tantrums", IMPPA early this week asked her to return the money the banner had paid her early this year.
