According to EURweb, Young said, “Although it’s a sad situation overall, it’s great news to find that Vesta’s death, as I said from the very beginning, was not drug related. Vesta did indeed die from an enlarged heart. As we know, an enlarged heart can remain undetected in the body for many, many years.”

Williams was responsible for hits like “Congratulations,” and “Sweet, Sweet Love.”

Most recently it was the singer’s dramatic weight loss that made headlines, after she dropped over 100 pounds, going from a size 26 to a 6. She had become an advocate for the prevention of childhood obesity.

Williams was laid to rest on Tuesday, October 4th at West Angeles Church of God in Los Angeles.
