Vow renewals can be wonderful, beautiful things: A public recommitting to spending the rest of your days with the love of your life. But sometimes they can also seem a bit like putting a bandage over a bullet hole: A last-ditch attempt to convince the world (and yourselves, usually) that your marriage is just fine, move along, nothing but love to look at here. In Hollywood, this happens all the time. Mariah Carey and Nick Cannon used to even renew their vows each new year they were married—until they didn't and then they weren't.
But nowhere is this phenomenon more prevalent than the world of reality TV, where everyone's always trying to keep the glossy veneer of their perfect lives up no matter how inaccurate that might be. Vow renewals with cameras rolling are an old trick to keep rumors at marital discord at bay. And they're also something of a kiss of death.
