Tab passed away tonight three days shy of his 87th birthday.
Glaser told the Los Angeles Times that Hunter collapsed in his arms at their home, and he was rushed to the hospital.
Among his many credits during that decade was his performance as Joe Hardy in the 1958 screen adaptation of Damn Yankees.
At the age of 15 Hunter ran off to join the Coast Guard, but was dismissed from service after it was discovered he had lied about his age. "He was athletic, more like a 60-year-old not an 86-year-old". The film helped introduce Hunter to a younger audience, some of whom were unfamiliar with his pin-up past.
Hunter rose to fame with his roles in "Battle Cry" (1955), "The Girl He Left Behind" (1956), "The Burning Hills", "Damn Yankees!".More news: Wimbledon 2018: Roger Federer bagels and beats Adrian Mannarino
George Takei tweeted "Tab Hunter was so much more than a teen heartthrob - he was a celebrated actor, trailblazer and an icon for the LGBTQ community". With no dramatic training, he was cast in a minor role in the 1950 drama "The Lawless".
Hunter developed into a respected horseman and kept several horses in Santa Fe, where he lived for some time in the mid-to-late 1980s after he co-produced and starred in the locally filmed Western parody Lust in the Dust.
During that era, Hunter also was, briefly, a pop singer, hitting No. 1 with a cover version of "Young Love" that even he, in his later years, was hard-pressed to describe as anything but a cash-in.
Hunter made the reveal in his autobiography, Tab Hunter Confidential: The Making of a Movie Star, which was released in 2005.
"I thought, 'Look, get it from the horse's mouth and not from some horse's a* em *THR's Scott Feinberg in 2015".
In fact, as his star was soaring in Hollywood, Hunter was involved romantically with actor Anthony Perkins and champion figure skater Ronnie Robertson.
And Hollywood, in that strangely serendipitous way, has one final act of Hunter's life to replay: a month ago the studio Paramount announced it was developing a film from J.J. Abrams and Zachary Quinto about Hunter's relationship with Perkins. But Jack Warner pulled me back and said, 'Just remember this, today's headlines, tomorrow's toilet paper.' I'll never forget that.
