Doug Reinhardt Does Hawaii, Paris Hilton

Seriously, Doug, we hope you brought along enough protection. Those UV rays can be brutal when you get that close to the equator. Careful, man.

Paris Hilton showed off her bikini body as she hit a Hawaiian beach with shirtless Doug Reinhardt, her new boyfriend, on a sunny Tuesday afternoon.

As you can see, they wasted little time showing off their affection for celebrity gossip sites' attention one another as they frolicked in the waves ...

Paris Hilton clutches a shirtless Doug Reinhardt.

The ho-tel heiress said of her new mean: "Doug and I became friends about a year ago and we continued talking and hanging out ... He’s such a gentleman. So sweet and nice and elegant and smart and fun. I’m just really happy."

Lauren Conrad? Rolling in grave.

Granted he's just trying to screw his way to fame, but dude is slumming it big time. Click to enlarge more pics of Paris Hilton and Doug Reinhardt in Hawaii ...
