Sinead O'Connor and Barry Herridge

At least she can take comfort knowing her marriage isn't the shortest on this list. The ''Nothing Compares 2 U'' singer might have thought nothing compares to Barry Herridge, but it didn't work out. Still, it was a marathon next to some of the short-lived celebrity unions you'll see on the following screens. —Erin Strecker

Lauren Holly and Jim Carrey
Duration: 9 months
Sure, it lasted less than a year, but just the thought that a guy like Mary Swanson and a girl like Lloyd Christmas could end up together makes me desperately want to make love to a schoolboy. Wait, that's not what I meant. —BW
