There's been speculation recently that redheads may someday go extinct. Even if the science is dubious, the idea of a world without ginger hair makes us shudder. What a drab future that would be -- way too many of our crushes sport luscious red locks. Whom could we count on to get things fired up? While we pray for genetic longevity, let's take the added occasion of St. Patrick's Day to honor a selection of our favorite redheads.

If you know of any other redhead beauties who missed our list, feel free to upload a photo to our gallery and share them!
