Confirmed: Doug Reinhardt in Paris

Or just Tokyo. But The Hills star's rumored relationship with Paris Hilton is all but confirmed now that he's been seen accompanying her on a business trip.

Here's a picture of the new couple at the airport prior to their departure for the land of the rising sun, with Doug Reinhardt looking thrilled to be there ...

Upon arrival, the pair were greeted by adoring fans, who apparently don't have much better to do, as they walked out of Narita International Airport.

Paris Hilton is in Japan to promote Samantha Thavasa clothing for some reason.

Doug Reinhardt? He's just along for the ride. Of her. Come on. No one dates Paris Hilton for her personality. It's all good, but a fact. We're just saying.

What would Lauren Conrad and Amanda Bynes say about their ex jet-setting around the world with the ho-tel heiress? Probably not a lot, except to thank their lucky stars that they dated him before he started slumming it this hard.
