Céline Dion is sharing an inspirational message as she finds comfort in the power of love amid her medical struggles. The Grammy winner made her comments alongside a rare photo of herself with her and late husband René Angélil's sons René-Charles, 23, and twins Nelson and Eddy, 13, on March 15, International Stiff Person Syndrome Awareness Day. Dion has not performed a concert in almost four years and canceled a world tour due to her health battle.
