Talking about the item number, Farah tweeted: "Have woken up 1 hour earlier than alarm in xcitemnt. 'Joker' ad out n I'm shootng an item song 4 'Shirin Farhad...' bt this time I'm dancing! surreal."
"Shirin Farhad Ki Toh Nikal Padi" also stars Boman Irani opposite Farah and is the story of a 40-plus unmarried man and a woman. The film hits theatres Aug 24.
Farah is the name behind super hit item from "Chhaiya chhaiya" to "Munni badnaam", "Sheila ki jawani" to "Anarkali disco chali" and the soon to be out "Kaafirana" from her husband Shirish Kunder's "Joker".
Director Sujoy Ghosh found it difficult to digest the news that Farah is doing an item number and tried confirming it with her. To this Farah tweeted: "Yess sujoy!! u may have 2 change the definition after Boman and me dance in it!"
