Anticipation for Celine Dion's return to the stage has reached a fever pitch in Paris.The singer is just days away from her Paris residency, which kicks off Saturday, marking her first concert series since her stiff-person syndrome diagnosis in 2022.Dion previously took the stage for a performance at the 2024 Paris Olympics opening ceremony.One fan in Paris told ABC News, "I love Celine. It's my life."Another fan said, "If you would look at the definition of 'comeback' in the dictionary, you have Celine Dion's photograph right there."The Grammy-winning singer, 58, first announced a 10-show Paris residency in March, describing the opportunity to perform again following her diagnosis as a birthday gift to herself.She has since added additional shows to the residency for a total of 26 concerts, running through May 2027.Celine Dion steps out of her hotel at the Royal Monceau Hotel, in Paris, September 5, 2026.Hans Lucas/AFP via Getty Images"This year, I'm getting the best birthday gift of my life…I'm getting the chance to see you, to perform for you once again in Paris, beginning in September!" Dion said in a statement in March. "I'm feeling good, I'm strong, I'm feeling excited, obviously a little nervous, but most of all, I'm grateful to all of YOU! I love you all and I'll see you soon!"ABC News entertainment contributor Kelley Carter put Dion's miraculous comeback story into context in an interview that aired Thursday on "Good Morning America."Popular Reads"I think a lot people thought that her performing career was over, that we had seen the last time Celine Dion was going to grace the stage, and luckily for the legions of fans that she has, that's simply not true," Carter said.Stiff-person syndrome is a rare neurological disorder that can cause muscle stiffness and spasms and is thought to be an autoimmune condition, according to the National Institutes of Health. It can cause symptoms including rigidity and stiffness of certain areas of the body causing unsteadiness, slower movements, and difficulties walking.Celine Dion steps out of her hotel at the Royal Monceau Hotel, in Paris, September 5, 2026.Dkpar/Mega/GC Images via Getty ImagesIndividuals with stiff-person syndrome can also have increased sensitivity to noise, which may trigger or worsen their symptoms.Treatments are available to help with symptoms, although there is currently no cure for the condition.Dion first revealed her stiff-person syndrome diagnosis in December 2022, saying in a statement at the time that the disease was "causing difficulties when I walk and not allowing me to use my vocal chords to sing the way I am used to."She added that she was working with a "great team of doctors" to build back her strength and ability to perform again."I have to admit it's been a struggle. All I know is singing. It's what I have done all my life. It's what I love to do the most," she said at the time.Dion told Harper's Bazaar in August this year that she experienced symptoms for 17 years before receiving a formal stiff-person syndrome diagnosis.To prepare for her Paris residency, she said she committed to an intense training routine -- 90-minute Pilates sessions three times a week and ballet classes with a local company two other days each week -- and rehabilitation, which includes "new meds, physical therapy, vocal therapy, [and] immunotherapy," according to the outlet.She added that she is embracing being back at work again after years of health struggles."I'm honest, and it's not always pretty," she told the outlet. "Sometimes it's happy things, sometimes it's sad, but it's called life."
