I just came across a photo of her absolutely gorgeous son in some random article online, and then looked up who his father was, because the article didn't mention. And then I thought, interesting, you would think that if a woman is a world-famous supermodel, no man in existence would deny paternity if given the chance - but turns out there was actually a schmuck who did.
Considering he hurled himself off his balcony this year, I would guess the man had many demons.
