Something similar happened with the origins of glam rock and the rise of androgynous fashion among performers. With the origins from performers like Marc Bolan , T.Rex, Slade, etc.
I think Micheal Jackson also got the idea (or at least hopped on the trend) from them. Especially since other artists like Prince, David Bowie, Depeche Mode etc. were also capitalizing on the popular 'gay alien from outer space' image in the 70's and 80's, from very different music genres.
Velvet Goldmine was a very good movie about that. Everyone in the entertainment industry basically borrow from each other in one way or the other.
