Irene Cara was known for her role as the title character in Fame and Flashdance in the 1980s. Her age was 63.
The news was announced on Cara's social media account on Saturday by her publicist, Judith Moose. "A cause of death is currently unknown," she said.
"Irene's family has requested privacy while they grieve," Moose wrote. The legacy of her music and films will live on forever."
In the Bronx neighborhood of New York City, Cara was born into a working-class Puerto Rican and Cuban family.
She appeared regularly in the 1970s children's show The Electric Company as a child actor.
A future generation of artists was influenced by Cara.
Seth Rudetsky says watching Cara on screen as a child helped shape his career goals.
