Young and El Moussa became engaged last July. The proposal took place on a beach just after the pair celebrated their 1-year-of-dating anniversary. They both took to social media at the time to share heartfelt tributes to each other and explain how their love story unfolded.

"From the first day I met you, to our first date and our second date when we decided to commit 100% before we barely even knew each other. But we knew what we had was special. We had that butterflies in your tummy, can’t eat, can’t stop smiling soul mate love," Young wrote.

The "Selling Sunset" star revealed that before meeting El Moussa, she had "given up hope" about finding love.

El Moussa also admitted in his tribute that before meeting Young, he was "a lost and broken man" who didn't think he would find love again.

"I just love you to the moon and back. You are my everything and you complete me," El Moussa gushed. "I'd be lost without you. HAPPY ONE YEAR ANNIVERSARY MY LOVE!!"

Back in November, El Moussa spoke to Fox News where he dished on his second shot at marriage. The TV star admitted he's "a completely different man today than ... I was a few years ago."

In addition to surviving cancer, he credited his divorce from his ex Christina Anstead for forcing him to grow as a person.

"My mental health was in the gutter for years," the real estate investor described. "And I worked really, really hard to get it out of the gutter and to be where it is today, to be happy, engaged, in love, [but] it was a lot of hard work."
