Céline Dion performs emotional cover of 'Over The Rainbow' in tribute to her mum after her passing

Céline Dion’s mother, Therese Tanguay Dion, passed away at the age of 92 on Friday.

Therese - who was affectionately known in her native Canada as "Maman Dion" - was reportedly surrounded by her family, including Céline, at the time of her passing.

However, the 'My Heart Will Go On' hitmaker did not want to miss her Friday night show, so she went on stage as planned, addressing the sad news with a stunning cover of 'Over The Rainbow'.

"I'm pretty sure that you heard the news about my mum passing away early this morning," she said to the audience.

She went on to reassure fans: "But I'm doing okay and we're all okay."

Celine added that she knew her mother had been ill for quite a while and that she had received a call from her mother's nurse a few days earlier to tell her "her time was coming soon."

"So last night I joined my brothers and sisters in Montreal, and I spent the evening at her bedside.

"We told stories. We sang songs. We hugged each other and we said our goodbyes.

"We are pretty sure that mum waited for us to all be together one more time."

It has been an emotional week for the 51-year-old singer, as Therese's death came just three days after the fourth anniversary of the death of Céline Dion's husband, René Angélil, and one day after the fourth anniversary of the passing of her brother Daniel.

Celine first met René in 1980 when she was 12 and he was 38. They eventually got married in December 1994.

Sadly, René's passed away in January 2016 when he lost his battle with cancer.
