Christie Brinkley Reacts to Ex-Husband Billy Joel's Brain Disorder Diagnosis: 'You're Our Piano Man'

Christie Brinkley is reacting to her ex-husband Billy Joel‘s brain disorder diagnosis.

Last week, the 76-year-old “Piano Man” singer announced that he is cancelling all of his scheduled tour dates after he was recently diagnosed with normal pressure hydrocephalus (NPH).

A few days later, Christie, 71, wished Billy well by giving a heartfelt shoutout on Instagram, sharing a post of her and her daughter Sailor, whose father is Peter Cook, attending one of Billy‘s concerts.

“Dear Billy, the whole Brinkley gang is sending you lots of love and good wishes for a full and speedy recovery. I was looking for some cute photos of you and Alexa to send you, when I came across this clip from a recent concert. It made me laugh ..but it also reminded me of all the joy you create, and all the sensational sing a longs you’ve lead,” she captioned the post.

“You turn an arena of strangers into a living room full of friends as we all sway in unison. I’m sure I’m speaking for everyone in that room when I say please take good care of yourself, we all want you back in that white hot spotlight, you’re OUR piano man
And we’re always in the mood for your melodies And we all hope you’re feeling alright!
We Love You, the kids, me and an arena or two!” she added.

Christie and Billy married in March 1985, and welcomed daughter Alexa in December 1985. Despite divorcing in 1994, the former couple has remained close.

In April, Billy serenaded Christie by singing one of his hit songs to her at his concert.
