Video: Billy Joel sings ‘Uptown Girl’ to Christie Brinkley at concert

The divorced couple reminisced on old times last week at the Piano Man’s concert at Madison Square Gardens.

Joel sang “Uptown Girl” at his show Thursday night while Christie had a front row seat.

Brinkley, now 60, famously starred in the music video in 1983.
