Groom plays video of bride cheating on him at their wedding. Safe to say marriage is over.

It is one of those stories that leaves you feeling so very unsure.

According to local Singapore media, a groom has exposed evidence of his wife cheating at his own wedding reception.

Allegedly called “Aman”, the groom was giving a speech to wedding attendees when a slideshow of their relationship was cut short by footage of his wife going into a hotel room with another man.

Media said the couple were “behaving intimately” in the recording.

Originally, Aman had gotten in touch with a private investigator, Ms Zhuo, to confirm suspicions he had about his then-fiancee.

"[I] 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," Ms Zhuo said.

"[I] spent six weeks monitoring the fiancee before reporting back to her client."

Ms Zhuo was then shocked to receive an invitation to the wedding, but she only understood her client's intention when the recording was played for all to see.
