It's her body...she can do whatever she pleases. If she's comfortable in her skin, and has never known anything different, then it's the right choice for her.
If it's the same lady I seen interviewed on TV she used to shave daily, use hair removal creams, hormones etc....but it just got too much so she decided to accept the way she was.
Sounds like a modern day freak show. Not the sort of thing that should be public entertainment in this day. Those involved deserve more respect than to be gawped at by those who find "reality TV" adequate viewing. Even if being paid "big bucks".
