American vocalist Mary Wilson, a founding member of the Supremes, died yesterday at the age of 76.

Her publicist, Jay Schwartz, announced that Wilson died suddenly at her home in Henderson, Nevada, although no cause of death was stated.

Wilson was a member of the Motown Records vocal trio--along with Florence Ballard and lead singer Diana Ross--when it hit the charts in the sixties with a string of songs composed by Motown's Holland-Dozier-Holland writing team. 

Some of the group's biggest hits include "You Can't Hurry Love", "You Keep Me Hanging On", "Love Child", "Baby Love", "Someday We'll Be Together", "Where Did Our Love Go", "I Hear a Symphony", and "Stop! In the Name of Love".

"I was always proud of Mary," Motown Records label boss Berry Gordy said in a statement released after Wilson's death. "She was quite a star in her own right and over the years, continued to work hard to boost the legacy of the Supremes.… She was a trailblazer, a diva and will be deeply missed."

Here's a video of the beautiful Wilson--along with the equally stunning Ross and Ballard--performing my personal fave Supremes tune, "You Can't Hurry Love", on The Ed Sullivan Show in 1966.

Notice how Ross loses an earring at the 2:05 mark but recovers it without missing a beat.

Those Supremes were one class act.
