She is -- simply put -- absolutely spectacularly beautiful.
And she's also the mother of two children, which when looking at her, seems unlikely to the point of nearly impossible. But it's true.
She's definitely a successful model (her Web site lists several affiliations) but she's got such world-class beauty and body, I'm surprised she's not with a top-line fashion range, like Victoria's Secret (admittedly, that's the top of the mountain), or at least a house like Ultimo or Agent Provocateur. She is, according to her Web site bio, the face of the Colombian lingerie brand Besame. I did a quick check and didn't see her, so maybe that's historical by now.
Enough with the text, let's get to the pics. She has a fabulous butt, and if you like that kind of thing, do an image search and you'll get plenty of views of the Posada posterior.
