Rene Angelil, singer Celine Dion's husband, manager and mentor, has died at 73, according to a statement on her website.
Angelil died at home in Las Vegas on Thursday morning after "a long and courageous battle against cancer," the statement said. "The family requests that their privacy be respected at the moment; more details will be provided at a later time." Authorities also confirmed the death to the Associated Press.
The couple had faced his cancer head-on for years.
That same year, Dion put her Caesars Palace residency on hold and canceled a planned Asian tour. "I want to devote every ounce of my strength and energy to my husband's healing," she said that August, "and to do so, it's important for me to dedicate this time to him and to our children."
After the 2013 surgery, "Rene could not talk, and he could not swallow; the surgery was major," the 47-year-old singer revealed in March 2015, when she finally returned to performing. "It was Rene's wish that I come back."
She further explained, telling Entertainment Tonight, "I'm his favorite singer in the world. And I'm his wife. And I'm the mother of his three children. And we have the same passions. We love each other so much."
At the same time, Dion told USA Today, "I'll say [to him], 'You're scared? I understand. Talk to me about it.' And Rene says to me, 'I want to die in your arms.' 'OK, fine, I'll be there, you'll die in my arms.'"
The couple, who'd been linked romantically since she was 19 and married in December 1994, had three children together: Rene-Charles, 14, and twins Eddy and Nelson, both 5. Angelil also had two adult children from a previous relationship.
