The 71-year-old singer took to Twitter to share a stunning throwback photo of the designer with the words, "Remembering L'Wren on her birthday Photo by Jean Pigozzi."
The black-and-white photograph shows Scott flaunting her statuesque figure and long legs while sitting in a chair at what looks to be a recording studio.
His tribute also comes shortly after the one-year anniversary of the designer's suicide, which occurred on March 17, 2014.
Scott hanged herself in her Manhattan apartment. She was 49-year-old.
