All-American Christie Brinkley was one of the most popular models of the early '80s. She graced the cover of the Sports Illustrated swimsuit issue three times in a row, became the face of Cover Girl, and hawked everything from Diet Coke to Clairol. As her youthful looks turned into middle-aged wrinkles, she cashed in on the infomercial circuit, shilling for Total Gym fitness machines alongside martial-arts demigod Chuck Norris. In recent years, she's spent her time on a number of standard-issue ex-supermodel pursuits—writing fitness books, launching a perfume, designing sunglasses and toddler toys, and dabbling in political activism. Brinkley has been down the aisle—and back to the courthouse—four times. The consecutive grooms were, in order: Jean-François Allaux (whom she divorced in 1981), Billy Joel (inspiring "Uptown Girl," but ending in 1994), Richard Taubman (lasting only a year), and architect and former model Peter Cook (whom she married in 1996, but divorced in a bitter, affair-tainted—but ultimately lucrative for Brinkley—settlement a decade later). Brinkley has three children, one with each of her last three husbands.
