Christie Brinkley has a suggestion for anyone considering marriage. "You could get married, like, 'We'll see if you want to renew it in five years,'" Brinkley, 71, said on the Thursday, August 7, episode of the "Are You a Charlotte?" podcast. "Every five years, go, 'Do you want to renew?'" She added, "That way, if you're getting bored or whatever, you can get out of it without all the lawyers and all that stuff." The supermodel has been married four times. She first wed Jean-François Allaux in 1973 before they split eight years later in 1981.
