The Flip or Flop star married British television host Ant Anstead in a secret "winter wonderland" wedding on Saturday.
El Moussa, 35, and Anstead, 39, wed in a ceremony at their house in Newport Beach, CA with 70 surprised guests in attendance, People magazine reported.
The couple reportedly told their friends and family members to meet at the home to board a charter bus to take them to watch the Newport Beach Christmas Boat Parade. However after they arrived at the home, the guests discovered they were actually attending El Moussa and Anstead's wedding.
El Moussa and Anstead exchanged vows at an altar in the front yard with all of their children -- they each have two from prior marriages -- in attendance.
"We wanted to make it about the kids," Anstead told People. "It's the six of us. We're a blended family so it was really important for them to be a part of it."
El Moussa is mother to her daughter Taylor, 8, and son Brayden, 3, with her former husband Tarek El Moussa, while Anstead has a daughter Amelie, 15, and son Archie, 12, from a previous marriage.
"We wanted it to be rustic romance," El Moussa told People of the ceremony. "It was just perfect for us. Everything we wanted."
El Moussa wore a lace dress by designer Ines Di Santo and told the magazine she plans to take her new husband's surname.
"It has a nice ring to it, doesnâ€™t it?" she said. "Christina Anstead. We couldn't be any happier!"
According to El Moussa, trying to keep the wedding secret resulted in a few anxious moments.
"Every day we were checking the Internet to see if anyone found out," she said.
"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."
