Therese Dion, the mother of Titanic singer Celine and affectionately known as "Maman Dion" has died at the age of 92, the performer said on Friday.

"Maman, we love you so much… We dedicate tonight’s show to you and I’ll sing to you with all my heart," said the singer, who was to perform later in Miami.

Therese Dion was the wife of Adhemar Dion, who died after a long illness in 2003, and the mother of 14 children, the youngest of whom, Celine, has sold almost 250 million albums.  

She launched her 12-year-old daughter's career when she sent a cassette recording of her singing to Canadian music producer Rene Angelil in January 1981. He was impressed by her voice, and took her on. They later married, in 1994.

Therese Dion hosted a cooking show on television for many years, launching her own line of dishes called "Pates de Maman Dion".

She also launched a foundation to provide school clothes and supplies to underprivileged children in Quebec. 

Quebec Premier Francois Legault paid tribute to "a remarkable woman, so generous, so loving, who devoted her entire life to the well-being of her family." 

"Our greater Quebec family weeps at her departure," he added.

The grandmother of 32, Dion had 48 great-grandchildren and was great-great-grandmother to six others, TVA said.

Celine Dion is currently on her first international tour in a decade, promoting her album "Courage."
