Happy birthday this month to Pamela Anderson -- who's turning 40! Last time we and Borat looked, she was both adorable and hot. Yes, many of Hollywood's hunkiest and most gorgeous are 40 or older and, as you'll see, hotter than ever. Here's a toast to those stars with just a little bit of worldliness to go along with their undeniable sex appeal. (Theodore Wood/Camera Press/Retna Ltd.)
