Nicky Hilton Paris Hilton sunglasses dress headband tan mac madison malibu county mart

After a long weekend of 4th of July partying, what's left for a couple of heiresses to do but shop?

Paris and Nicky Hilton hit up Planet Blue, Mac cosmetics and Madison at the Malibu Country Mart, before lunching on some raw fish at Tan Bui Sushi on Tuesday.

Miss Hilton had a bit of a scare on Monday, when her convicted stocker showed up at her Malibu pad, and disrupted the fun festivities with his creepiness.

The heiress called the cops and they quickly hauled the guy off. He's currently being held on $20,000 bail.
