Amanda Teague, 46, from Drogheda, Co. Louth, married the Haitian pirate named Jack earlier this year.
The wedding to her ‘soulmate’ took place on board a boat in international waters off the Irish coast.
However the Irish Mirror reports the couple have called it a day after less than a year.
Taking to social media, Amanda said: “So I feel it’s time to let everyone know that my marriage is over.
“I will explain all in due course but for now all I want to say is be VERY careful when dabbling in spirituality, it’s not something to mess with.”
The split is another blow for Jack, after he was purportedly executed for thieving on the high seas in the 1700s.
Pirates of the Caribbean fan Amanda previously told The Irish Post how she spent £4,000 to look like Captain Jack Sparrow, Johnny Depp’s character in the film.
