LOVE: Canada groom saves child from drowning in river [SEE LIVE PHOTO]

A wedding photoshoot in Canada took an unexpectedly dramatic turn as the groom leapt into a river to save a little boy from drowning, notwithstaning his dress.

Clayton and Brittany Cook were posing for wedding photos on a park bridge in Cambridge, Ontario, when the groom noticed a boy in distress in the river.

With no thought for his suit, Mr Cook jumped into the water and pulled the young boy on to the shore.

Their wedding photographer captured the whole rescue.

The images have since gone viral.

"His face was underwater and he was fighting, like he was really fighting," Mr Cook told CTV News.

"Luckily, he was only a little guy… and I honestly just sort of hopped him up."

Mr Cook said the boy appeared to have been pushed in by one of his friends.

Wedding photographer Darren Hatt said it was Mrs Cook who first noticed the boy, as she was the only one facing the river. But once she cried out, Mr Cook sprang into action.

"As soon as I could turn around he had already plunked him on the ground outside the river," Mr Hatt told the Media.

"So I just kept on capturing the story of the day, including this."

After being rescued, the boy appeared fine, if a little shaken, and went off with an older sibling.

Mrs Cook said her husband's quick thinking and selfless action were just some of the reasons she fell in love with him in the first place.

"That's Clay to me," she told CTV. "It's something he would just instinctively do."
