Family reunion! Christie Brinkley attended Celebrity Autobiography at the Guild Hall in the Hamptons on Friday with daughters Alexa Ray Joel, 30, Sailor Brinkley-Cook, 18, and son Jack Brinkley-Cook, 21
Billy Joel and Christie Brinkley - The pair wed in March 1985 and had daughter Alexa a few months later. The actress and singer divorced in 1994. "Billy's great," Brinkley told Ladies Home Journal. "He's godfather to my kids, Jack and Sailor, and you know there have been times when I have had to spend time with lawyers or whatever and he's babysat. He lives nearby, so he's like, 'Send 'em over here!'"
