The bridal party of Eric and Maegan Walber ended up in a lake after the dock they were standing on collapsed.
The group was gathered at 'Bay Pointe Inn' on Gun Lake in Michigan for wedding photos before they fell into the water.
Mr Walber explained to 24 Hour News 8: "We were out there for probably 30 seconds, standing on the dock, and it started to lean and tilt. We went right under."
The video was uploaded to YouTube by wedding guests and has been viewed more than 1 million times.
The bride retained a sense of humour about the incident, saying: "It makes for a good story, we'll be telling our grandkids."
