The couple's often-tempestuous relationship was detailed in Tina Turner's biography, which was the basis for the movie What's Love Got to Do with It? They split in the 1970s.
Speaking to PEOPLE in 1990, Turner admitted to being abusive in his marriage.
"All the fights Tina and I had were about her being sad about something," he said. "I get real emotional if you're worrying and don't tell me what it is. Then I can't think about nothing else. So I'd slap her or something like that."
Earlier this year, Turner told Jet magazine that he regretted many of his actions as a husband. "If I owe anybody an apology, that would be Tina," he said. "I put her through hell with other women. I regret it today, but I can't undo it."
As for Turner's reaction to the news of his passing, "Tina hasn’t had any contact with Ike in more than 30 years. No further comment will be made," her rep said in a statement to Access Hollywood.
Ike Turner married four times and had four children: Ike Jr., Michael, Ronald and Mia. Alongside his former wife, he was inducted to the Rock and Roll Hall of Fame in 1991.
