David Foster said, "My wife and I are in shock and truly devastated. Donna changed the face of pop culture forever. There is no doubt that music would sound different today if she had never graced us with her talent. She was a super-diva and a true superstar who never compromised when it came to her career or her family. She always did it with class, dignity, grace and zero attitude. She lived in rare air ... She was the most spectacular, considerate, constant, giving, generous and loving friend of 35 years. I am at a total loss trying to process this tragic news."
