Jenna Jameson (born Jenna Marie Massoli on April 9, 1974) is an American pornographic actress and entrepreneur who has been called the world's most famous porn star and "The Queen of Porn". She started acting in erotic films in 1993 after having worked as a stripper and glamour model. By 1996, she had won the three top newcomer awards from pornographic film industry organizations. She has since won more than 20 adult film awards, and has been inducted into both the X-Rated Critics Organization (XRCO) and Adult Video News (AVN) Halls of Fame.

Jenna tried to follow in her mother's career as a Las Vegas showgirl, but most shows rejected her for not having the required height of 5 feet 9 inches. She was hired at the Vegas World show, but left after two months stating that the schedule was brutal, and the money was terrible.

Massoli's boyfriend Jack encouraged her to apply for jobs as a stripper, and in 1991, though underage, she began dancing in Las Vegas strip clubs using a fake I.D. After she was rejected from the Crazy Horse Too strip club because of the braces on her teeth, she removed them with a pair of needle-nose pliers and was accepted. After six months, she was earning US$2000 per night, before finishing high school.

Her first stage name as a stripper was "Jennasis", a name she later used for incorporating as "Jennasis Entertainment". She chose the name "Jenna Jameson" to use as a model after scrolling through the phone book for a last name that matched her first name, before finally decided on Jameson for Jameson Whiskey, which she drinks.

Besides dancing, starting later in 1991, she posed for nude photographs for photographer Suze Randall in Los Angeles, hoping to get into Penthouse magazine. Jameson was paid $300 per day, without rights to the pictures. After her photos had appeared in several men's magazines under various names, Jameson stopped working for Randall, feeling Randall was "a shark" who had been taking advantage of her.
