The couple - who have been tipped to tie the knot at their French estate Miravel - haven't yet set a date for the wedding or made any specific plans and Brad admitted choosing the location will be less about picking somewhere meaningful for them and more about finding somewhere that suits both of their busy schedules.
He told 'Extra': ''We don't have a date ye. I don't know what's going to happen in two weeks never mind the New Year. We're such migratory workers that it'll be a matter of convenience location wise.''
Brad, 48, who has six children - Maddox, 11, Pax, eight, Zahara, seven, Shiloh, six, and four-year-old twins Knox and Vivienne - with Angelina, also revealed he is planning to work less as he gets older.
The 'Killing Them Softly' actor added: ''I'm coming up on that pretty quickly. I'm going to be 49 in a month and I see myself [slowing down with acting], I really love producing, I'll be less and less in front of the camera. ''
The lovebirds - who met on the set of 'Mr & Mrs Smith' - have previously stated they won't wed until same-sex marriage is legal in America and 'Moneyball' actor Brad, says proposing to 37-year-old Angelina in April made him believe more than ever that everyone should have the right to get married.
He added: ''Everyone should have [the right].''
