I don't think she would come out if she's Lesbian or Bi, at least not while she has plans to continue her show.
That sad fact is, her show would most likely be boycotted by droves of nuts so her ratings would plummet. The audience she attracts is primarily family orientated, and we all know what "Family Values" means to most people. It usually goes hand in hand with being anti-gay.
That somehow doesn't surprise me. I'm having to expand my storage capacity in order to accomedate for my large collection of stuff. Apparently 1.5TB isn't enough.
