You can hear the gasps from the congregation as a little boy takes a run up behind the bride as she walks down the aisle.
Seconds later he lands on her puffy white skirt and the bride is pulled backwards for a moment.
But as the wedding march plays on the bride keeps her composure and as the lad is dragged off, she continues her walk towards her husband to be.
Luckily for the bride, the boy gave out a roar as he ran towards her and she quickly turned round and anticipated the jump.
The boy was helped off the dress by a concerned guest as the congregation looked on aghast.
The video uploaded to YouTube in Friday, March 4 with the title ‘Mark and Tanya’s wedding’ and has already received more than 117,000 views.
It was the wedding of Tanya and Mark Monaghan and the boy in question was the bride’s four-year-old nephew Rhys.
The video of the wedding, which took place in Lucan, County Dublin, was originally uploaded to Facebook by Tanya’s sister Amanda Cunningham with the message: “That’s the funniest thing ever!
“Wedding to remember!! Congratulations Tanya!!”
Tanya’s other sister Antonia Malone told the Irish Independent: “Tanya’s friend picked him up and she continued on to marry the love of her life.
“We had the most fantastic day ever.”
