9. Rob Lowe
When Rob Lowe was 22 years old, a videotape surfaced of him having sex with two women. One was 22 years old, and the other was only 16 years old. Lowe claimed that he did not know that the girl was underage because he met her in a bar. The second half of the tape featured Lowe with a model and future film producer, Justin Morritt. This became the first commercially distributed celebrity sex tape.
