Heartbreaking Mary announced that she was working on a new solo material just two days before her death was confirmed.
Motown Records founder Berry Gordy said in a statement: “I was very shocked and sad to hear of the death of Mary Wilson of the Supremes, a major member of the Motown family.
“Supremes has always been known as’Motown Lovers’. Mary came to Motown in the early 1960s with Diana Ross and Florence Ballard.
“After the unprecedented No. 1 hit in a row, TV and nightclub reservations, they opened the door for themselves and for other Motown performances and many others.
“I’ve always been proud of Mary. She has been a pretty star in itself and has continued to work hard to enhance Supreme’s legacy over the years.
“Mary Wilson was very special to me. She was a pioneer and diva, and I will miss it very much.”
