Amanda Leigh and her husband Patrick Leigh of West Haven, Connecticut, were posing for wedding photos at the Mystic Aquarium when the hilarious picture was snapped by their wedding photographer.
Juno, an 11-year-old male beluga whale managed to place himself directly between the pair and flash a huge smile just as the photo was taken.
'That was just a lucky photo,' Amanda Leigh, 27, told Good Morning America.
According to the Mystic Aquarium website, Juno loves watching visitors at the underwater viewing area.
The Leighs say Juno made their wedding day - and they're planning a return visit to the aquarium for next year's Christmas cards.
