Nicky Hilton

If so, she's doing a pretty good job sticking to it!

The more fashionable Hilton sister ran errands in Malibu yesterday afternoon, and for the third time in the past week, she flashed us a smile. What's got her in such a chipper mood? Perhaps it's just the photogs telling her how lovely she looks?

Anyway, we love Nicky's ripped jeans, aviators and snakeskin peep toes, but we're not sure about the hat. What do you think...love it or lose it?
