Gouraguine, a marine biologist, is of Montenegrin descent, and it was believed that the pair had returned to his homeland for a private wedding ceremony.
The couple have been dating for seven years, and Sandé has previously vowed to take his name and henceforth be known as Emeli Sandé Gouraguine.
The singer, who won plaudits for her rendition of 'Abide With Me' at the Olympics Opening Ceremony, currently holds the best-selling album of 2012 in the UK with debut record Our Version of Events.
