Play met Vivienne when he was 14 years old and called it love at first sight!
The 3-time Masters champ announced the horrible news on his social media page Wednesday ... saying, "The unthinkable has happened."
"My childhood sweetheart, my rock, and my soulmate Vivienne has lost her battle with pancreatic cancer," Player said.
"I cannot describe the deep sense of sadness I feel at having lost the one person who has always meant the world to me."
“When we first met, I had no doubt it was love at first sight and it turned out to be a love story of a lifetime,” Player said. “I believe it will also be so when we are finally together again. Until then, I will miss my Viv dearly.”
