Before this normally blond party princess hit Jet Nightclub at The Mirage last night, she went goth, donning a black Elvira wig and fedora.
"It was obvious that she wasn't trying to fool anybody with her disguise," says a source of our wigged-out reveler. "There was some chatter in the club that it might have been some type of role-play fun she was having with her boyfriend. Whatever her intent, there was no denying that they were super hot for each other. They were all over each other, dirty dancing and kissing."

Surprise, surprise...it's Paris Hilton and beau Doug Reinhardt.
Paris is in Vegas filming season two of her MTV show, My New BFF, at the Hard Rock Hotel. According to a source, Doug has already appeared in some of the scenes.
Then again, her ex-boyfriend Benji Madden was in last season's show and look how long that lasted—so take Doug's current casting with a grain o' salt.
