DC Reveals Which Hero Is Gay.

In this article, DC says:

Today, we are pleased to announce that the mystery about the identity of the character in question is over. Appearing in next week’s EARTH 2 #2, Alan Scott is the only Green Lantern of Earth 2. A team leader with a Type-A personality and an appetite for justice, Alan also happens to be homosexual. And while his origins won’t be shown in full detail until issue #3, we can tease that a traumatic event will serve as the catalyst for him assuming his superhero identity as The Green Lantern.
