Just when you thought the Australian version of Married At First Sight couldn't be topped when it came to wife-swapping antics it looks like they've been outdone by the US series.
US MAFS expert Dr Jessica Griffin and former contestant Jon Francetic have confirmed they are engaged, just over a year after meeting while filming season six.
Jon was paired with bride Molly Duff, which in the US sees contestants take part in a real, legalling binding wedding.
Dr Griffin, a relationship expert, counselled Molly and Jon on their marriage, however they called it quits on decision day — the US MAFS' version of Aussie's vow renewal ceremony — and have since divorced.
