A WEDDING guest has been spotted flashing a VERY rude gesture at the bride in a viral snap.

Shared on Imgur, the older female guest - thought to be the mother-of-the-groom - can be seen posing alongside the couple and their other family members.

A mother-of-the-groom was spotted giving the bride the middle finger in a viral wedding snap

At a glance you would be forgiven for thinking it was your standard post-ceremony snap, but look a little closer and you realise it’s far from typical.

The woman in question can be seen, very subtly, flipping the birdie in the bride’s direction, while smiling at the camera.

The surrounding guests appear completely unaware of her actions, that weren’t spotted until after the couple’s big day.

The photo has since made its way on to Imgur where it has been viewed almost 6,000 times.

This not the first time that in-laws has been called out for their behaviour.

Yesterday, we told you about a bride-to-be who was left furious when her sister-in-law wore a white lace midi dress on her big day.

Taking to Reddit's wedding forum to ask for advice, she explained that despite there being a dress code, her sister-in-law had chosen to wear the style deliberately.

And other users were in solidarity with the bride-to-be, with one pointing out "the fact that she’s not showing you the picture means she knows what she’s doing is wrong".

And in other wedding news, brides have revealed what they wish they had done differently on their wedding day.

We also revealed a groom was slammed for showing up in ‘grass stained jeans’ to his nuptials – while his bride wears a full wedding gown.

And we showed you how a couple saved thousands on their wedding day by eloping and getting two STRANGERS to witness and photograph their £390 wedding.
