Marie Osmond took drastic measures to end her relationship with singer and Bee Gees' brother Andy Gibb.
In a new biography, "The Story of the Bee Gees: Children of the World," author Bob Stanley discusses Gibb’s romance with Osmond during the height of the "Shadow Dancing" singer’s drug addiction.
"He was doing tons of drugs, and she didn’t even drink Coca-Cola," record producer Albhy Galuten stated in the book.
"The Osmond family turned him away," Stanley wrote, adding that "Marie took legal action to stop him calling."

Osmond previously spoke about their relationship on "The Talk" in 2019 and said they’d known each other a couple of years and were dating when one night Gibb began calling her repeatedly.
"I could’ve probably done it better, but I just said, ‘We’re done,’" she said. "We hung up, and I felt really bad because it was something that I probably wanted to do in person, but it was just enough. And it was breaking my heart to see what he was doing to himself."
Gibb later told Osmond that moment was a "wake-up call." He went on to date "Dallas" star Victoria Principal. Their relationship ended when Principal forced Gibb to choose her or drugs and alcohol, according Stanley's book.

According to Stanley, many of Gibb’s relationships became strained due to his drug use, including those with his famous brothers and bandmates. His voice suffered as well.
"Andy’s voice had been wrecked by cocaine and Quaaludes," Stanley wrote."It cost him lucrative work."
Originally from Sydney, Australia, Gibb was the younger brother of Robin, Barry and Maurice Gibb, the Bee Gees. He was still a child when the band began releasing music.

"As early as 1982, he had been selling his belongings to make ends meet, flogging his jewelry for cash on Sunset Boulevard," Stanley wrote.
