Hilary Duff went diva on a couple of nine year olds over dinner in Richmond, Texas with big sister Haylie and their parents last Wednesday night.

Hil was approached two 9-year-old girls arrived carrying posters and T-shirts and hoping for autographs while dining at Pier 36 Seafood and Oyster bar.

“On their way out, the owner asked if Hilary would sign a menu for her daughter and she did,” says a spywitness.

But when the youngsters approached, the source says, “[Hilary] said, ‘I don’t really get to spend a lot of time with my family; sorry’ and walked out the door.

“She made one of the little girls cry.”
