Celine Dion has treated her fans to new music during her hiatus, which began after she was diagnosed with Stiff-Person Syndrome. The singer had been away from the limelight for several months due to the rare autoimmune disorder, which led her to cancel her scheduled European tour dates to focus on treatment and recovery.

In a delightful surprise, Dion has returned with a new song for her fans.

Celine Dion Debuts First New Song Since Health Diagnosis Celine Dion recorded the title track for Nick Jonas and Priyanka Chopra's upcoming romantic drama "Love Again," set for release on May 12. The song was released on Thursday, featuring Dion's gentle voice as she sings the heartfelt lyrics: "Cuz you don't have to move a mountain, just keep moving/ Every move is a new emotion/ And you don't have to find the answers, just keep trying/ The sun will rise again/ The storms subside again/ This is not the end/ And you will love again."

Accompanied by Rosaileen Scher's piano and Dan Wilson's acoustic guitar, Dion delivers the emotional lyrics in her unmistakable style. Wilson also produced the track for the film, which follows the story of a woman who struggles with the loss of her fiancé and uses her phone to maintain a connection with him after his death.

"Love Again" marks Dion's first musical release since she publicly revealed her diagnosis of the rare neurological disorder in December.

Understanding Celine Dion's Diagnosis Dion's Stiff-Person Syndrome diagnosis concerned her fans, leading her to cancel her European tour dates. Yale Medicine describes the rare autoimmune disorder as causing spasms and rigidity in the muscles of the torso and limbs. The episodes can occur randomly, but can also be triggered by certain stimuli, emotional distress, and loud noises.

Neurologist Richard Nowak explained, "People with Stiff Person Syndrome can run the spectrum from mild to severe, and a personalized approach to treating the disease is the best way to ensure an improved outcome." The exact cause of the rare condition remains unknown.

As Dion continues to fight the disease, a source told People that the singer is eager to return to performing. In addition to her battle with Stiff-Person Syndrome, Dion has also faced various health challenges in recent years, including patulous eustachian tube dysfunction and muscle spasms.
