They've been together six years. But now Gillian Anderson and her longtime boyfriend, Mark Griffiths, are going their separate ways.
Anderson, 43, isn't one to settle down for a long time. She was married to director Clyde Klotz, whom she divorced in 1997. They have a daughter, Piper, 17. She was also married to documentarian Julian Ozanne before splitting in 2006.
This most recent breakup comes a few months after Anderson spoke about having romantic relationships with women in the past years. "I decided to talk about it now because someone with whom I was in a relationship a couple of decades ago -- a woman -- passed away about a year ago," she told Out magazine.
"I was talking about her and, in the context of the gentle conversation we were having, I thought I would say that I have had a couple of relationships with women, but that wasn't my experience because I did have a choice. I always knew I still liked boys."
