Roselyn is the youngest of four siblings, having three older brothers. She received her primary education in San Juan. At a young age, she showed an interest in both dancing and acting and would put on shows for her family.
In 1991, at the age of 18, Roselyn moved to New York City, where she took classes in dancing, acting and singing. She returned to Puerto Rico and in 1992, she made her movie debut, having landed a small part as an island girl in the movie Captain Ron, which was partly filmed on the island, starring Martin Short and Kurt Russell.
Roselyn enrolled in the University of Puerto Rico, where, like her father and brothers, she was to study marketing. However, this was not her calling, and after three years she left the course.
