The King himself, Elvis Presley, was so smitten with former Olympics stud Bruce Jenner, now known as Caitlyn, that he gushed over him to then-girlfriend Linda Thompson, who would marry Jenner years later!
That is just one of many blockbuster admissions in A Little Thing Called Life, Thompson's new tell-all book, due out in August, which will expose Elvis' true feelings for Jenner, RadarOnline.com can reveal.
Thompson, 65, dated Elvis four years after meeting him during a Miss Tennessee beauty pageant that she had won. She reveals that when Elvis first saw Jenner on TV, he was buff and wearing a small pair of blue shorts.
"Linda was in bed with Elvis at Graceland when they first saw Bruce competing in the decathlon at the 1976 Summer Olympics in Montreal," dished a spy to Radar.
She confirmed in an interview that Elvis said, "Damn, if that guy is not handsome! I'm not gay, but damn, he's good-looking."

She joked to Elvis that she would "marry that guy someday," to which he quipped, "Yeah, sure, honey, over my dead body."
Elvis would die the following year in 1977. Four years later, Thompson, an actress with small parts on CHiPs and Starsky & Hutch, wed Jenner, now 66.
The mom of two from Memphis now lives in Malibu and has two sons from her marriage to Jenner — Brody, 32, and 34-year-old Brandon.
Her book will recount Jenner's painful confession of longing to become a woman when Brody was just 18 months old.
Despite therapy, the couple divorced in 1986.
"Bruce was a terrible dad to Brandon and Brody and ignored them for years," claimed a source.
"Linda is threatening to expose a lot in the book. She's hoping that she can get it out there before Caitlyn releases her own memoir."
