German fashion designer Karl Lagerfeld, who famously lost 90 pounds in 2001 on a regimen of Diet Coke and steamed vegetables, lent his silhouette to limited-edition, collectable bottles of Diet Coke last year. He's doing it again this summer, as it turns out, with three bottle designs instead of just one. The bottles will be sold individually, but whether or not they'll each be equipped with miniature fur coats this time around has yet to be determined. You'd think employing a special Diet Coke butler would be enough of a tribute to the brand, but I guess the gratitude of a man who can fit into his prom tuxedo again shouldn't be underestimated.
