Vidya Balan's lavani dance in Vidhu Vinod Chopra film

Filmmaker Vidhu Vinod Chopra feels that it is only a loose film that demands an item number to attract the audience and Vidya Balan's lavani number in his new film "Ferrari ki Sawari" is not for that purpose. Vidhu refutes calling it an item number. The film also stars Sherman Joshi and Boman Irani.
