"It's not true. Karan had approached me for that film, we had a talk on it, but nothing is official right now. Nothing is concrete. Karan has a script in mind and he has offered me a role, but it's too early to talk about it," Kareena told IANS.
"I will be more than happy to work with Karan. I am very comfortable working with him," she added.
Recent reports also indicated that Kareena's husband, Saif, will have an extended cameo in the film.
But Kareena says, "It is absolutely untrue."
According to rumour mills, the movie will be a period drama.
