Her long-time lover went missing at sea and was never found, her teenage daughter battled anorexia and the 59-year-old Australian singer confronted breast cancer.
But now that the blonde beauty has tied the knot, she hopes to have found happiness at last.
"I'm delirious. He's a wonderful man. I'm totally crazy about him. I love everything about him," the Daily Express quoted her, as saying.
The couple met 15 years ago but became romantically involved only last year on a South American jungle trip.
They were secretly engaged for six months before telling family and friends.
By fleeing to Peru, the couple kept their wedding small and private.
"We didn't want the stresses and pressures of a big wedding so we did it quietly and it was lovely," Olivia said.
