Married at First Sight ’s Jamie Otis & Doug Hehner Celebrate 5-Year Anniversary: 'People Laughed'

Jamie Otis and Doug Hehner’s love story has been far from traditional, but they wouldn’t have it any other way.

On March 23, 2014, the pair said “I do” within minutes of meeting each other for the first time on the reality television series Married at First Sight. On Saturday, they’re celebrating their five-year anniversary as a married couple.

“People laughed at us when they heard we were doing the show,” Otis tells PEOPLE exclusively in this week’s issue, on stands Friday. “Now here we are!”

As the first couple paired up by the show to make it to the five-year mark, Otis, 32, and Hehner, 36, recognize it’s not only a huge milestone from them personally, but also for MAFS.

“I don’t want to sound corny, but we owe our lives to this TV show and the experts that stuck with us,” Hehner says. “It was life-changing for us.”

“We’re very happy with where we are,” he adds. “We’re still growing as a couple.”
