MAFS expert engaged to groom from the show

One of the relationship experts from Married At First Sight US is engaged to a former contestant from the show, after his reality TV marriage fell apart.

Former MAFS groom Jon Francetic popped the question to Dr Jessica Griffin - who counseled him through his on-camera relationship - at the Grand Canyon this week.

Jon was originally paired with Molly on season six of the American version of the show, in which participants enter into a legally binding marriage, unlike the Australian iteration.

The couple called it quits at the final decision point - then Jon and Jessica reportedly began their relationship after filming wrapped. Jessica has since revealed she won't be returning to the show.

"I have always said, you can find love in extraordinary ways - you just have to follow your heart and be you," she wrote on Instagram.

"The right person will find you (if he's persistent enough and eventually hunts you down and won't take no for an answer.)"

"For the first time in my history of knowing him, Jon was at a loss for words and a total adorable mess on his knee. So, of course, I said yes - just helping a guy out.

"I love you with everything I have."

Jon also celebrated the news on Instagram, captioning a loved-up snap: "I just love how happy she looks".
