Gareth Thomas was married in 2011 and divorced in 2009. In 2009 Thomas announced publicly that he is gay. He told the Daily Mail, "I don't want to be known as a gay rugby player. I am a rugby player, first and foremost I am a man". He thus became the first openly gay professional rugby union player. In an interview with the BBC, Thomas talked about how he hoped that his coming out would mean that in the future, young gay rugby players would be able to come out and be accepted as a "talented gay rugby player". Thomas also said, "What I choose to do when I close the door at home has nothing to do with what I have achieved in rugby".
