The newlyweds credit El Moussa’s publicist and longtime friendCassie Zebischfor keeping the nuptials off everyone’s radar. “We literally owe this wedding to her,” says El Moussa. “She pulled it off.

Still, there were a few close calls. “Every day we were checking the internet to see if anyone found out,” she says. “Then the day we went to get our marriage license, the guy working was like hyperventilating, excited. We had to tell him this is a huge secret. No one knows.”

But the event went off without a hitch. “It was just perfect for us. Everything we wanted.”
