American singer, song-writer and piano man, Billy Joel has canceled all his upcoming concerts across England and North America after being diagnosed with a rare brain disorder.

He’s got a way about him. Now, the world wants him to know exactly what that means to them. Billy Joel announced last week that he had been diagnosed with normal pressure hydrocephalus, a progressive neurological disorder.

Christie Brinkley is showing support for her ex-husband Billy Joel following news of his recent brain diagnosis. The supermodel, who shares daughter Alexa Ray with the legendary singer, posted a video on Instagram Saturday -- just one day after Joel revealed he had been diagnosed with normal pressure hydrocephalus.
