Milap Zaveri's upcoming sex comedy "Mastizaade" will have a special romantic devotional song featuring former porn star turned Bollywood actress Sunny Leone in a never-before-seen avatar.

Leone will be seen seducing actor Tusshar Kapoor in the song, which will be a recreation of the "Baby Doll" song.

"In the film, Sunny's character (one of the twin sisters) is running after Tusshar and wants to have a one night stand but he needs commitment. She realises that he won't fall for her, so she comes up with an idea of wearing a sari that is beautiful and that's when the new version of 'Baby Doll' plays in the film," Zaveri confirmed, according to mid-day.

"The lyrics of the tune have already been changed. It's a great tune as well as the music continues to be tweaked by Meet Brothers. It's just like a parody on the initial song, a fun variation," he added.

Leone, who has worked in hugely successful movies like "Ragini MMS 2," "JISM 2" and "Leela Ek Paheli," will be seen in a double role in the movie. She had earlier said that she would be seen playing the role of a sexy girl, Laila, and a nerdy girl, Lily.

"This is the first time that I am playing twins - one is nerdy, while the other is sexy. I found that to be a great idea as India sees me more as Laila, but I'm actually nerdy - like Lily is - in real life. Maybe that's why Lily is closer to my heart because I got to act out a character who's closer to my personality," she had said in an interview with Daily News & Analysis.

She will also be seen doing a striptease scene inspired by similar sequences performed by Jennifer Aniston and Demi Moore in Hollywood movies. The movie also stars Tusshar Kapoor and Vir Das in key roles.

"Mastizaade" was supposed to be released in May but ran into trouble over its adult content, as HNGN previously reported. The Indian Censor Board, however, cleared the movie for release with an adult movie tag on Dec. 4.

The makers of the adult comedy postponed the release date again due to box office clash with adult thriller "Hate Story 3." It is now likely to release in January.
