Martin passed away of natural causes Friday at his home in West Los Angeles, his friend Beverly Scott told the Associated Press.
During his career, Martin appeared in more than 25 films, often as the romantic lead, including Ziegfeld Girl, and Casbah.
His popularity spanned from the late 1930s through the 1950s when Martin became synonymous with songs like "Stranger in Paradise," "La Vie en Rose," "Fools Rush In" and more.
Martin's first wife, 1937 until their 1940 divorce, was 20th Century Fox musical star Alice Faye. He then married fellow MGM star Cyd Charisse, who danced with such studio legends as Gene Kelly (in Singin' in the Rain) and Fred Astaire (in The Bandwagon), until her death in 2008. The couple met at a dinner party given by their mutual agent. They married in 1948 and later had a son, Tony Martin Jr., who died in 2011 at 60.
Martin is survived by his stepson from Charisse's first marriage and two grandchildren.
