Hilary Duff says she doesn’t regret dissing Faye Dunaway, usmagazine.com reports.

After Dunaway, 68, criticized Duff’s acting skills when she learned the singer, 21, was assuming her role in an upcoming remake of 1967’s Bonnie and Clyde, Duff sniped, “None of my fans even knew who she is.”

On Tuesday’s Bonnie Hunt Show, Duff defends her remarks.

“She started acting way later than I did so I think I have time to grow and grow with each project,” she says. “I am learning and work hard at my craft.”

While Duff admits her remark was mean, she says, “It’s not OK for people to take stabs at you and to say mean things for no reason.”

Hunt tried to comfort Duff on the episode of her talk show, saying: “I think even Faye went through a time, if you look historically, where some people might have said that about her,” Hunt tells the singer.
