Gay heads of state (as in, obligate homosexuals)

So, I just found out that Sayyed Qaboos bin Sa'id Al 'Bu Sa'id, the Sultan and autocrat of Oman, is a homosexual. Not that there's anything wrong with that! But that got me thinking, are there any other homosexual heads of state* out there? Please post a reference if you submit a candidate. * Prime Ministers count in a parliamentary democracy.
