It's Gigi's prerogative to do whatever she damn pleases, being the IRL Serena Van Der Woodsen of the world.
We somehow see this as being perfectly normal for her, because if you imagined us riding a horse butt-naked, it'd be weird.
Gigi has covered the December issue of Allure mag, where she is featured doin' a Daniel Radcliffe with a horse, but dang does she look good.
The cover is pretty fire too.
You do you queen.
