Ali Landry and Mario Lopez: 18 days

The actress and model Ali Landry would quickly regret exchanging rings with the Saved By The Bell star Mario Lopez despite them being in a six-year relationship. The pair got hitched on April 24, 2004, in front of 50 guests in a Roman Catholic ceremony at the exclusive Las Alamandas resort outside Puerto Vallarta, Mexico.

The reason she wished she hadn’t gone through with the ceremony? Well, Landry might feel the sacrament of marriage is very important, but Lopez surely didn’t as he had been sleeping with another woman just days before his wedding and she wasn’t the only one. Once Landry found out of his many infidelities, she would file for annulment just 18 days later.
