Billy Joel might be battling a brain disorder, but his daughter Alexa Ray says he’s still got it! She spilled that he’s “sharp as a tack” and hasn’t lost his memory or wit. Billy’s even switched up his diet (chicken over steak!) and is crushing physical therapy. Fans worried about his health can chill—he’s focused on recovery and feeling good, just working on his balance. Love to see a legend taking care of himself! #Health #BodyHealth #BillyJoel
