"I am not writing 'Delhi Belly 2', not writing or even directing 'Delhi Belly 2'," Rao told reporters.
A bold, youth-centric drama, "Delhi Belly" was directed by Abhinay Deo. It featured Imran Khan, Vir Das and Kunal Roy Kapoor in the lead.
The film ended with Imran's uncle and Rao's husband, actor-producer Aamir Khan, in an item boy avatar in the song "I hate you like I love you". At the end of the song, the banner of a new project "Disco Fighter", which will be directed by Rao, flashed on the screen.
Grapevine had it that the movie would be a sequel to "Delhi Belly". But Rao has put the speculations to rest.
The "Dhobi Ghat" director feels making a sequel to every film is not necessary.
"I guess if you have a good script as your sequel, it makes sense. But I don't think there is any point in making a sequel just because the first one's a success. Doesn't make sense," she added.
"Delhi Belly" grossed over Rs.26 crore in its opening weekend.
