Nicky Hilton in a sexy bikini in Hawaii

Nicky Hilton knows exactly what to do when the weather outside is frightful – pack your bikinis, fly to Hawaii and splash around in the Pacific Ocean! Why aren’t there any Christmas songs about that?

The other Hilton sister spent the day on the beaches in Maui with boyfriend David Katzenberg and in true Hilton sister fashion never removed her over-sized sunglasses. But none of us freezing mainlanders are gonna be complaining about her large, concealing eyewear when she’s willing to leave so much else unconcealed!
