My gay-dar did not go off on that one. I though that Neil Patrick Harris was just your typical metro-sexual. This morning I read a press statement he released to People Magazine that dispels any rumors (what rumors?) about his sexuality. He says in the quote that he is living a happy, fulfilled life. In the end, that is the only thing that really matters. It is sad that in this day and age people have to release statements about their gender preference.

"The public eye has always been kind to me, and until recently I have been able to live a pretty normal life. Now it seems there is speculation and interest in my private life and relationships.
"So, rather than ignore those who choose to publish their opinions without actually talking to me, I am happy to dispel any rumors or misconceptions and am quite proud to say that I am a very content gay man living my life to the fullest and feel most fortunate to be working with wonderful people in the business I love."
