The actress is currently working on Barfee with Ranbir Kapoor and Ileana D'Cruz.
She told The Times of India: "I think women, in general, are gaining more power. I've done films that had no heroes.
"People feel that actresses can't work post marriage, but look at [Aishwarya Rai Bachchan] who is still going strong, and Kajol and Juhi Chawla who are trending mums. These women are doing films and topping polls."
She added: "[Men over 40] are ruling the roost because they've earned it. If the audiences want to watch you, they'll watch you. They'll give you a lifespan of 30 years if they love you, and probably five years if they don't."
Chopra has played multiple roles in films like Saat Moon Kaaf and What's Your Raashee.
She has reportedly stalled the filming of Barfee in order to record her debut album.
