There seems to be a constant debate about the role of gender in movies recently. Should there be more female superheroes? Should gay characters only be played by gay actors? If that's the case, should the same be true of transsexual characters as well? Nobody seems to know for sure.
That's not to say that people haven't been playing around with the idea for a long time, though. The internet is a wonderfully creative place, and there are apps which can gender-swap you at the touch of a button. People have been putting those apps to good use on celebrities!
