51. The Kim Kardashian Sex Tape
Viral Date: February 2007
This is the defining moment of Kim Kardashian's career (besides being our cover girl) that introduced her to most of the world. And boy was it an introduction. Paris and Pam might have paved the way, but this is the greatest celebrity sex tape of all time. At the end of the day, when Kim walks the red carpet at an A-list event or presents at an awards show, we can relish in the fact that we've seen her getting busy. What's better than that? Not much.
YOU AUGHTA KNOW:
Kim K initially sued Vivid Entertainment over the tape, but wound up dropping the suit and settling for $5 million. Hun is a bonafide hustler.
