Céline Dion is mourning the loss of her mother, Thérèse Tanguay-Dion. 

Known affectionately known as "Maman Dion," the Canadian television personality died Thursday after being ill for some time, Dion's management confirmed to USA TODAY.

She was 92. 

"It is with deep sadness that Feeling Productions announces the death of Mrs. Thérèse Tanguay Dion," reads a statement provided by spokesperson Chantal Tessier Friday. "Mrs. Dion died peacefully at home last night, surrounded by her family."

Dion, who's currently on her Courage World Tour, dedicated her Miami concert to her mother on Friday and opened up about Thérèse's final moments during a moving tribute.  

"Two days ago, we got a call from the nurses who were taking care of her so well, saying that her time was coming soon," Dion recalled. "So last night, I joined my brothers and sisters in Montreal and I spent the evening at her bedside."

The singer continued: "We told stories. We sang songs. We hugged each other and we said our goodbyes. We are pretty sure that mom waited for us to be all together before departing."

Earlier, Dion shared a dated black-and-white family portrait on Instagram, featuring Thérèse, husband Adhémar-Charles Dion and their 14 children. The photo includes Dion, who is at 51 the youngest of nine girls and five boys. (Adhémar died in 2003 at age 80.)

Dion's mother died exactly four years after the singer lost her brother Daniel to cancer at age 59 on Jan. 17,  2016. Dion's husband René Angélil died from cancer three days before Daniel on Jan. 14, 2016, at age 73. 

"There is not a day that goes by without me thinking about your beautiful smile," Dion wrote on Instagram Tuesday, marking the fourth anniversary of her husband's passing. "We miss you, thank you for watching over us my love. I love you."

Dion and Angélil share 9-year-old twin sons Eddy and Nelson.
