Celine Dion’s sister, Claudette Dion, has denied rumors that the singer has lost her voice and has confirmed that she has been suffering from health problems for the past two years. Claudette also revealed that she is communicating with leading experts in the field of “stiff person syndrome,” which affects one person in a million, and is intensifying her reading and interviews with researchers to accelerate the search for treatment for the disease. The statement comes after a British tabloid claimed that Celine Dion is unable to stand on stage due to her health problems, causing concern among her fans. Likewise, the cancellation of her “Courage” world tour, after being diagnosed with the disease, is a necessary step in speeding up her recovery, according to Claudette. Celine Dion had postponed several concert shows in the past two years due to health issues, sparking questions from her fans about what could be happening with the international artist.
