The couple, who are currently vacationing in the Caribbean with their six kids, are planning to seal their union by getting matching wedding tattoos, reported OK! magazine.
"When Angelina Jolie and Brad Pitt finally take the plunge into matrimony this summer they are going to mark the occasion with something even more lasting than jewelry: They plan to get special tattoos. They're finalising designs now, but all they'll say is it will be 'very intimate'," a source said.
Apparently the A-listers are finding it tricky agreeing on a design.
"Angelina loves complicated and deeply thought-out tattoos that only have meaning to her and those closest to her. Brad likes something more visual and even suggested they do something a little silly, like a favourite cartoon character.
"They can't seem to decide what size and on which body part they should add the new decorations," the insider added.
They are staying with 22 relatives and a dozen nannies in the Turks and Caicos Islands.
Pitt proposed to Jolie in April but the location for their wedding is a secret.
