Alexa Ray Joel shared a recent update on her dad, Billy Joel’s, health after the legendary singer continues to battle a serious brain disorder.

The 76-year-old star shared that he had been diagnosed with normal pressure hydrocephalus, which impacts his vision, balance, hearing, and more.

The Riverside Way star, who is the daughter of Billy and his former wife, supermodel Christie Brinkley, spoke to Fox News about how her dad was incredibly resilient in the face of his great health struggles.

‘Unfortunately, I did not get the characteristic from him because I like to express how I am feeling always,’- Alexa mentioned. He does not whine, especially at this older age, she added.

She further added how she is appalled at her father’s patience and tolerance and his ability to remain calm without complaining, despite going through so much.

“He’s so cool about everything that’s taking place in his surroundings. “He’s always playing everything down as if nothing took place. Oh, I am fine, don’t worry. He does not worry!”- she shared in a shocked tone. The star is believed to be fully committed to his health and to modifying his lifestyle to be his best version to date. One of the major ones includes his diet, where he eats more veggies and fruits than anything else.
