Billy Joel Serenades Christie Brinkley with ‘Uptown Girl’ [VIDEO]

I'm so sad I wasn't in the audience at Madison Square Garden in New York City this past Thursday night.  Billy Joel performed, and in the front row stood his ex-wife Christie Brinkley, whom he serenaded with a song that started their relationship some 30 years ago.  Watch Billy sing 'Uptown Girl' to Christie!  I continue to hold out hope that these two will someday end up together again.  She really brought out the best in him!
