Celine Dion made a remarkable return to the stage at the 2024 Paris Olympics opening ceremony, marking her first performance since being diagnosed with Stiff Person Syndrome (SPS) in 2022. The 56-year-old singer performed Édith Piaf's 'L'Hymne à l'amour' from the Eiffel Tower, stunning audiences and drawing praise from figures like Kelly Clarkson and Canadian Prime Minister Justin Trudeau. Dion's appearance was particularly emotional given her SPS diagnosis, a rare neurological disorder that causes muscle stiffness and spasms. Despite the challenges, her powerful performance was a highlight of the ceremony, which also featured other acts like Lady Gaga in a pre-recorded segment. Lady Gaga opened the ceremony with a stunning French cabaret-style performance along the Seine River, singing 'Mon Truc en Plumes' by Zizi Jeanmaire. The event marked a historic first as an outdoor and floating ceremony on the Seine, featuring the Parade of Nations and attended by prominent figures, including First Lady Jill Biden.
