Sources allegedly told Celebrity Dirty Laundry that Anderson and Duchovny have been in a serious relationship for some time, and the 44-year-old actress has even moved her two children in with the 52-year-old "Californication" star. With few facts and no photos, we're inclined to believe these dating rumors are as much of a hoax as most UFO sightings, although both parties are single -- as Duchovny separated from wife Tea Leoni in 2011 and reportedly finalized the divorce quietly earlier this year.
The pair have known each other for nearly two decades, working together on "The X-Files" for nine seasons and two feature films as FBI agents Fox Mulder and Dana Scully. Is this one we know about, I say, the father of the two youngest children, or a new one? UPDATE: The truth is out there, and the truth according to David Duchovny's rep is that the rumors are false.

But after Anderson and Duchovny headed an event called “The Truth Is Here” at the Paley Center in New York to celebrate the 20th anniversary of , the suggestion that they are dating in real life is not that absurd.
At the event Gillian Anderson and co-star Duchovny conducted a questions and answers session via Reddit for their fans. In one of the questions Duchovny was asked if he thought Anderson was “hot” he replied: “Yes. It’s somewhat shocking.” Furthermore a source spotted the couple on their too and from the Paley Center event where they arrived and left, allegedly, holding hands.
After all these years, we want to believe they're a couple, but the website's "evidence" that the pair are romantically involved is paper thin. The actor's rep told MSN's Wonderwall that the rumors aren't true, but added that the former co-stars are still good friends.
In addition to claims from their unnamed source, the website argues that Anderson's hesitation to discuss her personal life with I ask if she has a partner at the moment.
We’re exclusively assured that the rumor of a “romantic beach getaway” between Duchovny and Anderson is “completely false.” We’re also told that Anderson has been in Belfast, Ireland hard at work shooting her TV series “The Fall.” Additionally, the “X-Files” co-stars have never dated, nor are they currently seeing each other.
X-Files co-stars Mulder and Scully, known in real life as Gillian Anderson and David Duchovny, may be dating. Usually such rumors of co-stars getting together for real are baseless and centered around speculation.

When the show originally aired from 1993 to 2002, some fans felt so strongly that paranormal investigators Fox Mulder (Duchovny) and Dana Scully (Anderson) should date that it’s believed to have coined the popular Internet phrase “shipping,” which means you root for two characters to end up together.
Partly, this phenomenon exists because loyal TV fans simply have a personal investment in characters.
Sorry, 'shippers, but David Duchovny says he and Gillian Anderson are definitely not dating.
