I think keeping your personal life by yourself is the best you can do, anyway. First of all, it IS private and has not to be carried out in public, and second, when there's an artist gay, bi, or whatever, he/she always has to live with that outing. That is, being asked about it in interviews all the time, and people looking first at their sexuality but at their talent. Honestly, that's just ridiculous, but the truth.
Like David Bowie once said - saying publicly that he is bi was the biggest mistake in his life.
