Who? Brazilian pop singer.
Real? Yes, she made at least two hardcore porn films.
The Brazilian pop singer Gretchen was born Maria Odete Brito de Miranda in 1959. Her first hit single was “Dance With Me” in 1978. Her first three albums went multi-platinum, and she released dozens of hit singles. She earned the nickname “Rainha do Bumbum” (“Butt Queen”) for her sexy music and sexy dance moves on stage. She has reportedly sold 15 million albums worldwide. Her popularity faded for a while, but rose again in the late 1990s and 2000s.
In 2006, Gretchen signed with Brazilian porn studio Brasileirinhas to make two hardcore porn films, released as La Conga Sex (evoking her 1981 single “Conga Conga Conga”) and Carnaval 2007.
