The actress recorded a song in a studio in Los Angeles recently, which will be released as part of the "Hisss" soundtrack and promotions.
"Mallika has recorded her voice singing two different songs. The first of the songs is composed and arranged by Julian Lennon, son of John Lennon from the iconic rock band The Beatles. Upon mixing of the track, the song will be sent to Mr. Lennon for approval," a source said in a statement.
"The second track Mallika recorded is arranged by German composer Alexander Von Bubenheim who provided the background score for 'Hisss'. Both songs have Mallika singing in a breathy, sexy style reminiscent of famed French actress Brigitte Bardot's legendary collaborations with musician Serge Gainsbourg," added the source.
"Hisss" soundtrack comprises of five songs and three dance remixes and is expected to release in India in mid-September.
Slated for an October release, "Hisss" is about a snake woman whose mate is captured by an American hunter and then she decides to take revenge.
Directed by Jennifer Chambers Lynch, it also stars Irrfan Khan, Jeff Doucette and Divya Dutta.
