AN elderly wedding guest caused a scene when she walked straight into a swimming pool - slap bang in the middle of the all the tables.

A video, thought to have been filmed in Spain, shows family and friends of the bride and groom milling around during the reception - with upbeat music playing in the background.

The elderly woman then wanders into the shot, dressed in a floor-length navy dress and clutching her handbag - and strides straight into the pool.

She didn’t seem to notice the huge body of water in front of her as she headed for tables on the other side - causing a huge splash in the process.

There are horrified gasps from fellow guests as they all rush to the poolside, with a woman heard screaming ‘mama’ in the background.

The bizarre clip was uploaded to Facebook group That's It I'm Wedding Shaming, where it’s racked up more than 150 comments.

People seem to think the elderly woman didn’t clock it was a pool, instead believing it was a dancefloor.

Commenting on the video, one person said: “Poor thing lol. She probably thought it was plexiglass covered.”

Someone else wrote: “She probably thought it was the dancefloor.”

But a third raged: “Who has a wedding here?

“What’s the draw for a poolside wedding? There’s so much unusable space, no one’s swimming clearly, and apparently it’s potentially dangerous!”

While this woman added: “My ex mil [mother-in-law] would have done that purposefully for attention lol.”

Meanwhile this bride was forced to quit her job after her boss refused to give her time off for her own wedding.

In more bride news, this woman was mocked for demanding all her guests owed her a gift, regardless of whether they're coming to the wedding.

While this bride blasted her make-up artist after she refused to style 10-year-old bridesmaid’s hair because she was crawling with nits.
