"Honeymooning with the wifey" he captioned the video, adding some heart and fire emojis for good measure.
El Moussa, 35, of HGTV's "Flip or Flop" with ex-husband Tarek El Moussa, met Anstead, 39, host of the British car show "Wheelers and Dealers," in 2017 through a mutual friend.
The pair managed to keep their engagement a secret, hoping to avoid attention from the paparazzi as they worked to blend their families. El Moussa has two children, Taylor, 8 and Braden, 3, from her previous marriage. Anstead also has two children, Amelie 15, and Archie, 12, from a previous marriage.
Right before Christmas, the couple invited 70 guests to their home in Newport Beach, California, under the guise of taking charter buses to see the Newport Beach Christmas Boat Parade. Instead, guests quickly realized they were actually attending a wedding!
A winter wonderland-themed ceremony was set up in the front yard and El Moussa yelled "surprise!" as she walked down the aisle in a lace Ines Di Santo wedding gown, according to People magazine.
"We wanted it to be a rustic romance," the bride told People. "We didn't want all the fuss. Just a quiet wedding without all the drama and paparazzi."
Now that they're hitched, it's obvious that the pair is ready to relax and revel in the beauty of Bora Bora and each other's company.
