It wasn't just the bride and groom taking the plunge at this wedding in the US state of Minnesota.

A hilarious video has captured the moment a wedding party fell into a lake after a jetty collapsed during their photo shoot.

Dan and Jackie Anderson had lined up their wedding party for a photo session an hour before they tied the knot last weekend.

But the group of 22 was too much weight and the decking slowly collapsed into the lake.

Videographer Megan Fritze caught the calamitous collapse on tape at the weekend.

The video shows the four bridesmaids closest to shore make a dash for dry land and sprint up the decking as the structure begins to creak.

As other guests arrived for the wedding, groomsmen and bridesmaids were still in towels waiting for their dresses and tuxedos to dry off.

Despite the unexpected swim, the ceremony started just 10 minutes late, according to local TV station KMSP-TV.
