In 1993 Lopez was accused of date rape, but prosecutors found no evidence to support the allegation, and multiple witnesses "contradicted the woman's account of her encounter" with Mario.
After six years of dating, Lopez married actress Ali Landry on April 24, 2004, in a Catholic ceremony at the Las Alamandas resort outside Puerto Vallarta, Mexico, but their marriage was annulled two weeks later.
