She obviously has fake boobs, but her ass also has a LOT of cosmetic work done to it. I've seen some of her early pictures (Pre-Selena Spice) where her ass was not as big as it became. In Latin America, big ass enhancements are the norm for these models.
Let's be honest, it's her very young look that is her main appeal. She's also a great performer, but time will tell whether she can transition away from her current niche.
Of all the 'teen' models that flourished in the mid-Millennium decade, Ariel is probably the only one who has aged the best or at least has continued to be as hot as when she began!
