She will feature with actor Jai in the number.
"She's not grooving to an item number. We have roped in for a special song that unfolds as a dream sequence of Jai's character, who dreams of dancing with Sunny in the film. We have tried to make the song colourful, but it is not vulgar," the film's director, Saravanarajan, told IANS.
"We narrated the dream sequence to Sunny and she liked it. We are planning to shoot the song in December," he added.
Also featuring Swathi Reddy, Kasthuri and RJ Balaji in important roles, "Vadacurry" is being produced by Dayanidhi Azhagiri.
Sunny is currently shooting for Kaizad Gustad's "Jackpot".
