The 59-year-old brother of award-winning Canadian singer Celine Dion died after a long battle with cancer on Saturday, two days after the death of Dion’s husband, her representatives said in a statement.
Daniel Dion, the eighth oldest of 13 siblings, “passed away peacefully” surrounded by family at the La Maison Adhémar-Dion care center in Québec, Canada, the statement posted on the singer’s website said.
Celine Dion, 47, asked for privacy after she announced on Thursday the death of her husband and long-time manager, René Angélil, at the age of 73 after fighting throat cancer.
Angelil, married to Dion since in 1994 and with whom she has three children, died at home in Las Vegas from cancer.
The couple have three sons, René-Charles, 14, and 5-year-old twins Nelson and Eddy.
Dion took two career breaks to look after Angelil after he was diagnosed with throat cancer, first in 2000.
Angelil was born in Montreal in 1942. After managing groups in Canada, he was approached to manage Dion by her parents when she was aged 12.
Last year, Dion told USA Today she was preparing for her husband’s death.
“When it hits me, it’s going to hit me,” she told the newspaper in August 2015. “But my biggest job is to tell my husband, we’re fine. I’ll take care of our kids. You’ll watch us from another spot.”
The couple renewed their vows at Caesars Palace in Las Vegas in 2000.
The Montreal Gazette says he mortgaged his house to finance her first album.
She has recorded 25 studio albums, and is the fifth-best-paid recording artist in the world, with a value of some $630m (£437m).
In 1999, her song My Heart Will Go On, from the soundtrack of the film Titanic, won two Grammy awards.
She has been a regular performer at The Colosseum Casino at Caesars Palace in Las Vegas since 2003.
She returned to performing last year after a year-long hiatus to look after Mr Angelil. He stepped down as her manager in 2014.
