In their new film "Material Girls," Hilary and Haylie Duff play bratty heiresses on a search for a conscience.
"They are materialistic, they do live this life where they don't care about too much and don't have very much responsibility," says Hilary about their characters which certainly made the two channel their inner Hiltons.
Perhaps taking a jab at Paris and Nicky, Hilary added, "there's a lot of people out there, they don't seem normal either. They just seem like they go about life."
Even director Martha Coolidge admitted "the phenomena of Paris" may have inspired the original writers but for the Duff sisters it was the chance to work together that made them sign on.
"It actually felt really normal and it was really easy for us," said Haylie, "We are really close in real life. We felt lucky that we had the opportunity to do it."
