The Potato Whisperer.
To be fair to Rob his homosexuality was well known in the music and entertainment biz and wasn't really advertised. When it was finally revealed to the public though literally nobody cared. Why? It's because Rob Halford is awesome.I actually did choose obvious gays for a reason, because the others, while also gay looking back on it, weren't obvious about it. Halford in particular you wouldn't have even thought " this guy is gay" because it had absolutely nothing to do with his persona.
But seriously, if you didn't realize Freddie Mercury was gay you were probably just oblivious. He wasn't at all closeted about it, his band was named Queen, I mean I was personally surprised when I realized he was gay, but I was oblivious. The man was an obvious and open homosexual, and he didn't give a shit if you knew it or not.
Jobriath and his insistence of being the "gay" rock star reminds me of this sketch:
