When a woman in a wedding dress burst into Stacey Owen's reception shouting "it should have been me" she thought her perfect day had descended into chaos.
Stacey's first thought was that it was an ex-girlfriend of her new husband Keri.
Her fears grew when the woman started hitting Keri with a bouquet of flowers, WalesOnline report.
But it turned out to be a set up by Stacey's maid of honour, Jackie Lewis.
Jackie had persuaded comedian January Rees to gatecrash the wedding, which took place on November 30 at Ty Newydd Country Hotel in Aberdare.
It was planned for about four or five months before the big day.
January stormed into the wedding reception after the couple's first dance shouting, and singing "it should have been me".
"I managed to persuade Jan to take part, it could have gone drastically wrong," Jackie admitted.
"Stacey expected some sort of surprise and I just wanted to do something silly.
"I was searching for ideas online when I came across videos of drag queens going down the aisle which gave me this idea."
Talking about the wedding, bride Stacey said everyone was terrified when the stunt first unfolded.
"I just thought what is going on as we had just done our first dance. At first the lights were dim and I couldn't see her face so I just thought it was one of Keri's nutty exes.
"But when the lights came up I could see Jan's face and I knew who she was then. My partner was terrified at first."
The 29-year-old said that performance would always be remembered by everyone who went to the wedding.
"We did see the funny side, the performance has had everyone talking.
"Everyone at the wedding was laughing and they were hiding when she was whacking people with the flowers.
"The whole day was brilliant, my partner was hiding behind me, he just said 'I hope she doesn't terrorise me' as he'd seen her live before as a stand up comedian."
January admitted she was really nervous as it was the first time she had ever done anything like it.
"Jackie phoned me and said 'Jan, only you can pull it off', but it could have gone either way. I got my old wedding dress from the attic and got in the car and drove to the venue.
"You should have seen the neighbour's face. Only the DJ and Jackie knew about it. At first the bride was shocked and she thought I was a crazy ex-girlfriend.
"The response has been amazing, everyone seemed to love it," she said.
