Rebel has taken to Instagram to announce she has been diagnosed with terminal ALS.

Terminal ALS (amyotrophic lateral sclerosis) is the final stage of a progressive neurodegenerative disease where motor neurons die, causing complete muscle paralysis and inability to breathe, usually resulting in death within 3-5 years of diagnosis. The body shuts down while the brain often remains fully conscious, necessitating hospice care for comfort and communication support.
