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 sons] 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!'"
