She looks like every other Puerto Rican...
Not quite. Most folks on PR are mullato/Trigueno, with noticeable African features (not a bad thing, btw :)). It is true, however, that most PR beauty queens tend to be more Mediterranean/European looking than the population as a whole. This is a commonality amongst most LA beauty contestants, btw.
The lovely young lass in question resembles the daughter of a former client of mine, who was based in El Salvador, but of Lebanese ancestry (the Lebs being disproportionately represented amongst the wealthy in Latin America). Unfortunately for me she was already engaged at the time. :(
