Are these the most awkward wedding moments ever?

Many married couples look back on their wedding as the happiest day of their lives.

But these toe-curling stories prove that for others it is a far more stressful affair.

Wedding guests took to anonymous confessions app Whisper to share the most shocking and awkward moments they have ever witnessed.

From prostitutes interrupting the ceremony to the maid of honour losing the rings, the scenes would be enough to give any bride or groom-to-be nightmares about their own big day.

One guest shared a particularly scandalous story about when the groom's ex-girlfriend showed up and claimed he was the father of her child. Another told how a former flame had arrived to try and put a stop to the nuptials.

Here, FEMAIL from Daily Mail shares some of the most horrifying examples...
