About Nina Mercedez

Mariza Villarreal (born November 10, 1977) is an American entrepreneur, fitness model, wellness influencer, former competitive bodybuilder, and retired adult film actress, producer, and director. She is best known by her former stage name "Nina Mercedez", under which she built a successful career in the adult entertainment industry before transitioning into health, fitness, and motivational content.

Although some more recent online sources claim Villarreal was born in Mexico, the most consistently documented biographical information throughout her career identifies her birthplace as Corpus Christi, Texas, United States.

Raised in South Texas, Villarreal has spoken about working a variety of jobs—including as a waitress, retail employee, bartender, and promotional model—before beginning her career as an exotic dancer. Her success on the competitive dance circuit earned her numerous titles, including Miss Nude North America, Miss Nude International, Exotic Dancer of the Year, and Miss Nude Universe, helping launch her into the adult entertainment industry.
