Velázquez decided to join the
University of Puerto Rico drama department as a young woman. She was interested in theater and participated in some notable plays such as "La Mandrágora" ("The Mandrake"), "El Efecto de los Rayos Gamma Sobre la Flor Maravilla" ("
The Effect of Gamma Rays on Man-in-the-Moon Marigolds") and "Los de la Mesa 10" ("Those on Table 10"). Velázquez was so popular among the same Puerto Rican audiences, that she, like
Luz Odilia Font, had a unique contract that allowed her to work at two television channels at the same time. Soon, she was cast for the
canal 7, "Teleluz" show "Como Ser Feliz En El Matrimonio" ("How to be Happy During Marriage"), which was shown midday during weekdays. However, after the show ended its run, she opted to stay at Telemundo instead. Velázquez chose for her character to be named like her, and so she played the eponymous "Rosita", the meddling neighbor of "JuanMa" (played by
Juan Manuel Lebron) and "Wiwi" (played by
Awilda Carbia).
Benito Mateo played Velázquez's husband, "Benny". In 1980, Paquito Cordero debuted another comedy show at Telemundo Puerto Rico, canal 2. The new show was named "
Los Kakukomicos" ("The Kakucomics", a name that closely sounded like Telemundo's station's call-sign of WKAQ). Velázquez was hired to play "Gloria Notesmande", the best friend and collaborator of
Otilio Warrington's character, "Cuca Gómez". == Personal life and death ==
