Gillian Anderson, David Duchovny : the two stars of the X Files became one of the most popular TV pairings of all time. However, from now on we may be referring to them as Gillian Anderson, David Duchovny , the hottest new celebrity couple in town, if gossip website Celeb Dirty Laundry are to be believed anyway.

No sooner has Anderson split from her boyfriend of six years Mark Griffiths, than she's apparently moved in with Duchovny in Los Angeles. A source revealed that the pair have actually been in a serious relationship for some time now and she and her children are enjoying living with the Californication star. It's certainly been a long time coming for the pair, whose chemistry on The X-Files was often the source of tabloid stories concerning the extent of their relationship. They worked together between 1993 and 2002, before starring in the movie version of the sci-fi crime show in 2008. Anderson has twice been married and had one child with her first husband and two more with Griffith. David married Tea Leoni in 1997, with the couple having two children together before reportedly getting quietly divorced in 2009. Back in May this year, the New York Post spotted the actor apartment-hunting in New York, fuelling speculation that he was now single.

During an interview just a couple of weeks ago with The Sunday Times Magazine, Anderson appeared to stumble over an answer about her personal life. When asked if she had a partner at the moment, the actress replied, "Um.yes.umm.umm", before adding, "Say yes". When asked if the partner was the father of her two youngest children, Anderson added, ", no, why do you ask me?". Hmm.
