The famous paranormal crime buster duo reportedly was fed up with one another. Working close for a long duration of time can take a toll on any individual. It was rumoured that the two dated, but both confirmed in an interview that they were never romantically involved. In 2008 David Duchovny mentioned how he and Anderson couldn’t bear the sight of each other. In his own words “familiarity breeds contempt”. Gillian Anderson wasn’t also happy how Duchovny was getting paid more.
