The 41-year-old actress, who tied the knot with Pepe Baston last month, said she didn't do anything in terms of wedding planning, reported People magazine.
"I didn't have to do anything. There was no wedding planning, it planned itself.
"Pepe's sister did it. She's an event planner in Mexico. We automatically used her and that's how we're kind of able to keep it quiet, because we kept it in the family. She really did everything," Longoria said.
The actress said the wedding process was more stress-free than she expected it to be.
This is the third marriage for Longoria, who was previously married to actor Tyler Christopher and NBA star Tony Parker. Baston has three children from his previous marriage to actress Natalia Esperon.
