Well, that’s a “polemic” subject. I’m a fan of Matt since 2009/2010, and what I know is:
The blogger Perez Hilton started with the rumors; and in 2006 Matt was in a radio (Howard Stern Show) saying that he is not gay. I never heard this audio, never read something more about this and I don’t care about it.
For me, all that matters is that Matt is an amazing, special and incredible person and a very talented actor independently of his sexuality and I respect and support him.
So, I can not answer if Matt is gay or not, because it only matters to him and I don’t know much about it. Ok?
