Christie Brinkley and Billy Joel have been the friendly exes and that is on display after his recently shared medical diagnosis.

"We all want you back in that white hot spotlight," wrote Brinkley, who shares daughter Alexa Ray with the singer.

And we’re always in the mood for your melodies and we all hope you’re feeling alright," Brinkley wrote to the musician, referencing the lyrics from one of his most famous songs Billy Joel can always count on Christie Brinkley to be in his corner.
