Pitt and Jolie met on the set of "Mr. & Mrs. Smith" back in 2005. They have three biological children (the twins Vivienne and Knox, and daughter Shiloh) and three adopted children (Maddox, Pax, and Zahara).
Brad and Angelina had previously stated they would NOT get married until gay people could get married too -- but admitted their children were pressuring them to tie the knot.
This will be Brad's second marriage and Angelina's third. Angelina was previously married to actors Jonny Lee Miller and Billy Bob Thornton. Brad was previously married to Jennifer Aniston.
