"Nargis flew down from Hungary to shoot the song in Chennai. She's doing an item number with Prashanth in the film. We are shooting the song with Nargis at Binny Mills featuring over 100 dancers alongside her," a source from the shoot told IANS.
"Saahasam" is the Tamil remake of Telugu blockbuster "Julayi".
Nargis also took out time to tour the city.
"She spent few hours touring the city. She even visited Prashanth's gold store and spent time with his father Thiagarajan," the source added.
She had also shared a picture of meeting a friend here at a star hotel on her Twitter page recently.
"Saahasam", which is produced by Thiagarajan, is being directed by Arun Raj Varma and it features Tamannaah Bhatia in the lead role.
