Kate Gosselin, Jon Gosselin

For their ninth anniversary in August 2008, Jon and Kate Gosselin renewed their vows in a lavish ceremony in Hawaii – all for their TLC reality show, of course. After the ceremony, Kate explained to her eight kids that the renewal signified a “promise” that mommy and daddy “will always be together.” So much for that!
