Billy Joel: 'He's a Real Fighter,' Daughter Says About His Health

Billy Joel's daughter, Alexa Ray, has provided an update on the 75-year-old artist's health, who was diagnosed with a brain condition. She said that Joel is undergoing regular physical therapy and has adjusted his diet.

'He's in physical therapy regularly and he's doing really well,' Alexa Ray told The Hollywood Reporter. 'He's also lost weight, because he's on a specific diet. I'm so proud of him. He's a real fighter and he has so much stamina, he is determined to stay healthy and take care of himself. He's a fighter. He's always been a fighter,' she added.

Last January, Billy Joel returned to the stage for a brief appearance in Florida, performing the songs 'We Didn’t Start the Fire' and 'Big Shot.'
