The couple tied the knot on July 15, 2011, on Sir Richard Branson’s private Necker Island in the Caribbean. 

Shortly after saying “I do," Nick caught up with PEOPLE and explained that seeing Vanessa for the first time as his wife was a moment he'd never forget.

“It literally took my breath away,” he shared. “It’s a moment you fantasize about, and I was certainly not disappointed.”

In the years since, the duo have been busy raising their three little ones: sons Phoenix, 6, and Camden, 10, and daughter Brooklyn, 8. They've also kept viewers entertained on Netflix's Love Is Blind, which they've been co-hosts on since 2020.

Nick and Vanessa celebrated 12 years of marriage in July. The One Tree Hill alum reflected on all that's happened since saying "I do" — thanks to their "beautiful life together with three amazing kids."

"Vanessa, not a day goes by that I’m not grateful for your love, your patience, your understanding, your fight and determination, your support, and your willingness to always work through the tough times," he wrote alongside photos from their wedding day. "While we don’t always have it all figured out, nor claim to, we know that together we can find our way."
