It's crazy to think about it now but, in her prime, Pamela Anderson was a girl we want to stay 25 years old forever. The buxom Canadian first found fame as Tim "The Tool Man" Taylor's assistant on Home Improvement before strapping on the red one-piece for Baywatch, but Anderson's insane natural beauty shone like a beacon to dudes entering puberty in the late 80s. Unfortunately, hard living took its toll on her, both physically and mentally. Here's a tip for ladies out there: if you want to stay hot, don't marry a dude from a hair metal band. They'll suck all of the sexiness right out of you, leaving you a crazy withered husk.
