Billy Joel and Christie Brinkley divorced 20 years ago, but they clearly still have love for each other.

During Joel's August 7th concert at Madison Square Garden in New York City, he sang one of his biggest hits, "Uptown Girl." As any fan knows Brinkley starred in the music video. 30 years later, he dedicated the song to her. Brinkley clearly enjoyed herself. She instagrammed a picture of herself beaming up at the stage with the caption "he's still got it!"
