A gift bag containing nearly $10,000 worth of Christian Dior shoes, sunglasses, handbags and perfume was taken from outside the Hilton home, spokesman Elliot Mintz said Monday.
The younger Hilton "spent three or four hours shopping to put together this wonderful collection of things for her mom," Mintz said.
A delivery person set the package down outside the home's gate to ring the intercom when a passenger in a passing car snatched the gifts.
"A fellow just whizzed by and grabbed the package," Mintz said.
The Hilton family celebrated Mother's Day by going out to dinner, he said.
