Kimberly and Diamond Dallas Page
Diamond Dallas Page was a huge WCW star in the 1990s, so he was a rival to WWE. When with that company, he married Kimberly and created a horrible nickname for her (Diamond Doll). His character had to be mean to her all the time, and they ended up divorcing in 2005.
