Her son, Michael Cannatta, told Deadline that his mother died of natural causes in her sleep at her home in Los Angeles.
An official cause of death has not yet been announced by authorities.
Roberts remained active in Hollywood up to her death. She will appear in two movies set to be released this year, Old Soldiers and The Red Maple Leaf, according to IMDB. She also appeared in a Super Bowl commercial earlier this year.
She recently spoke to TMZ, about a month ago, when she was going to the movies in Los Angeles. She told the gossip site she wasn’t feeling great, but TMZ said she was as “witty as ever.”
