Happiest day of their lives? Eye-catching wedding moments guests will never forget (but not always for the right reasons!)

Everyone strives for their wedding to be the most memorable event on the social calendar, but unfortunately that doesn’t always turn out to be the case.

My Health Gazette has collected a gallery of failed weddings from around the world, and some of them will get you in trouble.

In one case, a bridal party posed for a photo shoot with an unusual backdrop of portable toilets.

And while some wedding moments are laughable, others are almost humiliating.

Elsewhere, a wedding guest distracted others from the bride’s outfit after she turned up in a white ball gown.

Most people choose to be in nature for their wedding photo shoot, but an unconventional bride and groom chose to take their photos next to portable toilets

At another wedding, the couple posed for photos on the beach after the service, only for a speedo-clad swimmer to photobomb the photo.

Guests also giggled at the custom-made cookies at a ceremony in the US that appeared to spell ‘DIE’, given the bride and groom’s initials ‘D’ and ‘E’.

Elsewhere, a wedding guest asked others in an online chatroom about the best way to prevent a ceremony from going ahead.

But instead of speaking out at the right time, the guest wondered if a smoke bomb might be a more effective route, sure to make a wedding unforgettable.

Here, FEMAIL looks at the most hilarious and cringe-inducing moments captured on the ‘happiest day’ of people’s lives…
