A man took revenge on his cheating partner by playing a video of her cheating on him at their wedding.

Guests at the wedding in Singapore were astonished when they saw a montage of the couple's relationship so far suddenly cut into footage of her going into a hotel room with another man.

Local media reported that the couple were seen "behaving intimately" in the tape.

The man reportedly then told the woman to go to Hell before storming out.

It was not clear whether the wedding had taken place by the time the groom made the revelations about the bride's affair.

The groom stunned his guests, and the bride, by playing the footage during the wedding reception

He had hired a private investigator a few weeks beforehand after suspecting his fiancee was cheating on him.

The man, like his apparently cheating partner unnamed in reports, was reported to be a businessman.

The investigator he hired, a Ms Zhuo from Ajax Investigation And Security Services, spoke to Singaporean media about the case afterwards.

The montage showed surveillance images of the bride entering a hotel room with another man, not the groom

Ms Zhuo, 42, said she had expected that the customer would use the information she provided about the bride-to-be seeing another man in hotel rooms to call off the engagement.

So she was astonished to receive an invitation to his wedding.

She said she spent six weeks monitoring the fiancee before reporting back to her client and it was only when she saw the tape of the woman appear at the wedding that she understood his motivation.

The name of the man with whom the fiancee was apparently having an affair was not revealed.
