Vogue Williams' new documentary, Is Monogamy Dead?, aired on RTÉ2 last night and viewers were very taken with one couple in particular.

The TV presenter shone a light on the concept of monogamy and relationships in the modern world in the show, and while she investigated a series of unconventional relationships, it was clear which side of the fence the recently-wed star came down on.

Williams had some engaging and often hilarious chats with couples in open and polyamorous relationship and viewers were very taken with the insights she presented. 

While thoroughly entertaining throughout, Williams and viewers at home became emotional when she met Des and Mona, a couple who have been married for 56 years.

When Williams asked them the secret to their happy marriage, Des became choked up as he described how much he loves having his wife by his side.

As if that wasn't lovely enough, viewers then watched as Des demonstrated his makeup skills on Mona, which he has learnt due to his wife's failing eyesight.

Viewers were quick to deem them the ultimate in #RelationshipGoals.

Commentators were less enamoured with Mary, a 44-year-old woman from Manchester who has a husband, a live-in partner and two boyfriends, which prompted Williams to jokingly refer to her as a "greedie boots".

Williams, who welcomed her first child with husband Spencer Matthews last week, has hinted that they will want to add to their brood again soon.
