Following news of her death Thursday night, her friends, colleagues and admirers have taken to social media to express their grief over the loss of the legendary singer.
"More like family than friend was Natalie,” Dionne Warwick said in a statement to ET. "My heart aches. My sincere condolences to her family and may she now rest in peace."
GRAMMY producer Ken Elrich also shared this memory with ET, "Natalie possessed one of those magical voices that grabbed you from the first note. It could sound like honey, but when she wanted to belt, she could keep up with the best of them. In a way, and not just in lineage, Natalie was the connector between the great singers of her father and Ella's generation, and the great female voices who were to dominate in the last 25 years. I'll never forget when we did 'Unforgettable' as a duet with her father's recording on a GRAMMY hall of fame show, years before she recorded it. Magical!!!"
