The team of " Madhouse" (earlier titled "Sadda Adda") really wanted a Delhi girl for the item number in their movie, but lack of time lead them to hire Iran-born-and-Sweden-raised Maryam Zakaria to perform for the song.
The song was shot at a pub in Noida, and while speaking to us, the movie's producer, Rajeev Agarwal, said, "We already had our dates from the production team and couldn't delay the shoot, so we selected Maryam because she is a fabulous dancer and has Indian looks too."
The movie's director Muazzam Beg was supervising the shoot, and told us that we shouldn't look at the song as just another item number, even though the song is called " Dilli Ki Billi". He says, "The song is about Delhi women – how they are edgy yet bitchy, but you'd always fall in love with them. The item number is picturised in a pub where the actors have gone for a night of fun. So it's contextual." We later saw Maryam practicing her moves in a corner all by herself.
Maryam has perform very well in Dilli ki Billi song of Sadda Adda , song has got huge response because of music and Maryam dancing.
