Chung previously reminisced on her Halloween wedding while chatting with PEOPLE last year.

"Fun fact is my husband and I got married on Halloween, and so one of the requirements that we asked our guests for was that everyone come in costume to celebrate at the welcome dinner to kick off that weekend," she recalled.

"It was such a great icebreaker and it was so fun to see everyone come and get so creative with their costumes, most of them being DIY costumes."

Earlier this year, Chung opened up to PEOPLE about spending time with their twin toddlers, enjoying the evolution as the boys began talking up a storm.

"They're stringing together sentences. The expanding of the vocabulary is pretty neat," Chung shared.

"One of our kids, this morning, just said blue for the first time. And it's like, 'You're starting to understand colors? You know another color besides yellow?'" Greenberg laughed.

Noting some of their favorite phrases are "blue car" and "bye ducks," the twin mom said, "It's been really funny to see them connect the dots that way."
