Tarek El Moussa and Heather Rae Young have been getting festive by participating in some of their favorite holiday activities as a family.

Last year, the Flip or Flop star, 39, the Selling Sunset realtor, 33, and his two kids — daughter Taylor, 10, and son Brayden, 5 — whom he shares with ex-wife Christina Anstead, dressed up in matching Christmas pajamas to pose for holiday photos. This year, they’re making it a tradition and doing the same — and sharing the photos exclusively with PEOPLE.

“Matching Christmas pajamas is a new tradition for us as a family. One day they are going to look back on these pictures of all of us in silly outfits and I hope it makes them laugh,” El Moussa says.

“We love creating memories with the kids,” Young adds. “This year, it was even more important for all of us to have a sense of fun during such a serious time.”

For their first holiday season as an engaged couple, Tarek and Heather will be hosting Christmas at their house with their immediate family, they told PEOPLE exclusively. Taylor and Brayden will be celebrating with them for Christmas Day and New Year’s.

“We're hosting Christmas, then the day after Christmas we're heading out to the desert in La Quinta [Calif.] where we have a house to spend a few days and enjoy New Year's there,” El Moussa tells PEOPLE of the family’s plans. “Then I think the second week of January we're taking the kids skiing in Utah.”

Tarek and Heather have also hopped on the Elf on the Shelf bandwagon, with one elf for Taylor and one for Brayden. “One night the elves got into the brownies and chocolate milk and made a mess for the kids to find in the morning!” Young jokes.

El Moussa and Young met on the Fourth of July in 2019 in Newport Beach, Calif. The pair confirmed their relationship with joint Instagram posts in early August, and El Moussa shared that he had already introduced Young to his kids. Young calls herself the kids' "bonus mom," and became involved in their lives immediately after she and El Moussa began dating.

In April, the pair began renting a home together in Newport Beach, and in September, PEOPLE confirmed they had purchased a home of their own, which they are currently in the process of renovating.

They got engaged on July 25 while celebrating their one-year anniversary with a boat trip to Catalina Island and are planning a wedding for 2021.
