New York- Has Paige Davis gone into hiding?

The 35-year-old fix-it vixen – who presides over The Learning Channel’s house-swapping show, “Trading Spaces,” in which neighbors redecorate each others’ homes – had been scheduled to go on the “Today” show this morning for an interior-design segment.

But Davis abruptly canceled the appearance after Lowdown reported this week that she’s the object of hot cyberspace rumors concerning an allegedly steamy homemade video.

Yesterday, Davis’ PR rep told Lowdown: “Paige is certain that the tape, if it exists, is a hoax. Her lawyers are aggressively pursuing the issue.”

But Davis’ rep stubbornly refused to identify said lawyers and responded with a terse “no comment” when asked if a lawsuit is in the offing.

As for the surprise “Today” cancellation, Davis’ rep insisted it’s unrelated to Lowdown’s revelation and explained mysteriously: “Paige could not appear on the ‘Today’ show due to a change in her schedule” because of the holidays.

Rumors of the alleged 1997 video first surfaced on the Celebrity Nudity Database (www.cndb.com), where anonymous reviewers described a variety of activities allegedly involving Davis and “a boyfriend,” including an intimate shower scene in which she sings “I Feel Pretty.”

As one reviewer put it, “Her body is incredible. She clearly works out and has no tan line. … The tape should be hitting the Internet soon.”
