Model, actress, and entrepreneur Christie Brinkley is the mother of three: daughters Alexa Ray Joel and Sailor Lee Brinkley-Cook, as well as only son Jack Paris Brinkley-Cook. Jack was born on June 2, 1995, and to celebrate his 26th birthday, Brinkley shared rare and heartfelt photos in a sweet post. The tribute, posted to Instagram, offers followers a special glimpse at her son's life throughout the years. This comes after Brinkley tended to be selective of sharing photos of her children.
