Céline Dion and Andrea Bocelli combined forces — and their voices — on Saturday night.

The singers made an appearance during the star-studded One World: Together at Home special, during which they graced viewers with an intimate performance of their 1999 song “The Prayer” from their respective homes.

Dion, 52, and Bocelli, 61, were joined by classical pianist Lang Lang with Lady Gaga and John Legend singing, as well.

The musical icons’ contribution to the special will help raise awareness through the COVID-19 Solidarity Response Fund to support local and regional charities providing food, shelter, and healthcare to those in need amid the ongoing health crisis.

The “My Heart Will Go On” singer has been doing her part to stop the spread of the virus by postponing her “Courage” tour through the end of April and urging others to stay at home and be safe.

During her time in self-isolation, the artist has been sharing messages on social media, reminding people to “take care of each other” and thanking those on the frontlines for their “heroic work.”

“There are so many heroes out there around the world who are going to work every single day, risking their lives, and sometimes sacrificing their lives for the rest of us,” she said in an emotional Instagram video Thursday. “These people have families and loved ones who they’re worried about, but they still go out to work to save us, to serve us.”

“We salute your bravery and we pray for you,” Dion shared, holding back tears. “We are eternally grateful.”
