2) Pamela Anderson and Tommy Lee
Here’s one for the oldies crowd. Famously married after knowing each other for 96 hours, Anderson and Lee have somehow kept their relationship going for almost two decades. Sure, they’re not married any more, and have fought, made up, pressed charges, argued and rehabbed so often, it’s hard to keep track. But at least they’re still friends, united in raising their kids and by a once-famous, not slightly nostalgic-seeming, sex tape.
