Perez Hilton broke this story on Coral (Back to New York), who has presumably come out as a lesbian after years of dating men including some on reality television.
The interview talks about how Coral has recently decided to venture toward women and decided not to do so on reality television because it'd be kinda mean to come out to her parents on a reality television show. She was seen cavorting with Abram (South Pacific) on a Challenge, which is a relationship that she later denied ever happened.
The interview she gives with Outlook Magazine identifies her as coming out more and doing more GLBT events.
She also states that she is mulling an offer to be on the next Challenge, which is reportedly scheduled to be filming now or relatively soon.
