Who? Brazilian reality TV personality & pornstar.
Real? Yes, she made several hardcore porn films.
Marcia Imperator first became famous for appearing on the Brazilian variety/reality TV show Eu Vi na TV (literally “I Saw on TV”). One popular segment on the show was known as “o Teste de Fidelidade” (“Fidelity Test”), in which an attractive actor flirted with someone in a committed relationship on hidden camera, often leading to in-studio arguments when the footage was screened. Marcia Imperator was one of these undercover flirters.
After her reality TV gig ended, Marcia Imperator signed with porn studio Brasileirinhas to make three hardcore porn films. Her first two releases were titled Fidelidade à prova (“Fidelity to the Test”) and Noiva Infiel (“Unfaithful Bride”) to exploit her Eu Vi na TV fame.
Fidelidade à prova was a bestseller, and Marcia Imperator quickly became one of the most popular pornstars in Brazil. She has continued working in the biz after her initial contract ended, both in Brazil and in Germany. You can find several of her films online: Marcia Imperator at AEBN and Marcia Imperator at Hot Movies
