The couple got married in July 2023 after five years of dating. They first met in 2017 and Dylan entered her DMs with her phone number shortly after.

But Barbara waited six months before making contact, and then talked for three months before they met in China.

“After three months of talking, I flew to China to see him,” the supermodel told People.

'I was supposed to work in China and then they canceled the job. I was like, 'Are you crazy to still want to go and see yourself?', because I was so excited.'

He was on board, asked her to come, and then wanted to be exclusive from the first moment.

It took Barbara a while to get to know him, but after a while she relented and the rest is history.

'I sat down, took a deep breath and thought, “What am I waiting for? There is no one I love more than him and he has everything I need,” she said.

Four years later, Dylan got down on one knee and proposed in September 2022.

They did not publicly confirm their engagement until June 2023.

On July 15, 2023, the couple married in an intimate ceremony at his parents' property in Hungary, which doubled as an event venue.
