The 56-year-old star stopped performing live after she was diagnosed with Stiff Person Syndrome - a progressive neurological disorder that affects her muscles - in December 2022, but Celine made her long-awaited return during the spectacular opening ceremony in Paris on Friday night.
The award-winning star closed the ceremony - which also featured an eye-catching performance from Lady Gaga - with a rendition of Edith Piaf's 'LHymne lamour'.
Celine performed on a platform underneath the Eiffel Tower, which was adorned with the Olympic rings.
The event featured a flotilla that went along the Seine river in Paris, and was witnessed by a host of world leaders, including French President Emmanuel Macron.
Celine was spotted in Paris earlier this week, sparking speculation that she would perform during the opening ceremony.
