Gaga. I feel she is bisexual or at least has had some sort of experience with the same sex and I feel that she is always with Gay friends etc. You get my point
Gaga tried to make herself a gay icon which makes her not a "real" one IMO, since gay icons are always chosen. Although kind of synthetic, I'd have to say her, considering how she sacrificed an era to attempt to catapult herself into the hearts of gays everywhere, and it actually worked on a few younger ones.
