The 'Moneyball' actor and his actress fiancee - who raise six children together - already each have multiple pieces of body art but want to commemorate their union with some "weird" new inkings.
A source said: "[They are deciding] with what and where they will ink themselves to mark their long-awaited marriage.
"Brad really wants to do something special, and frankly, a little weird to mark the occasion, and they want to get the exact same design, in the exact same spot in their bodies."
The couple are planning to have the designs etched somewhere that isn't always visible and Brad, 50, is particularly enjoying coming up with the right piece.
