After just a few years, top model Nate Hardin has officially QUIT! When asked why, the #sexy yet #mysterious man said exclusively to us that: "[I've] seen it all. You know the time's come when working with #gorgeous women and being flown to exotic locations becomes something you dread. I'm just ready to find someone I #love and explore the world through their eyes." Is that someone on #usbachelorette show, Nate? What about your on again, off again girlfriend, #hot supermodel Kay Pierce?
