As odds go, she's probably dead by now.
I mean, if you consider that perhaps 50% of the current population is women, and 50% of them more or less belong in the period of age women are most often considered attractive... You get maybe 1-2 billion potential choices without taking out "not my type", "just ugly", and so on.
But it's a safe bet given the conditions about 1/3 of human population lives through that at most half billion of "chicks" would presently fit the bill.
Now you look at the whole history of people, a few thousand years back, and consider how many people have died. Sure, the population wasn't nearly as high as it is now, but in all those thousands of years since the earliest humans started looking more or less like humans, I'd say the majority of "hot chicks" as numbers go are already dead and you're committing mental necrophilia (not really, but hurrr).
More on topic, Orlando Bloom is totally a hot chick.
