The couple reportedly married in a private ceremony attended by family and friends. Pitt and Jolie obtained a marriage licence from a local California judge, who also conducted the ceremony in France.
Pitt and Jolie's six children were also in the wedding. Jolie walked the aisle with her eldest sons Maddox and Pax. Zahara and Vivienne threw flower petals while Shiloh and Knox served as ring bearers.
Jolie, 39, and Pitt, 50, started dating while working together on the 2005 film "Mr. And Mrs. Smith." The couple got engaged in April 2012 after seven years of dating.

Jolie and Pitt's wedding caps years of rampant speculation on when the couple would officially tie the knot. Pitt once said that he didn't want to marry until gay marriage was legal, but in recent years, both said they intended to. They were engaged in early 2012 after some seven years together.
"It's an exciting prospect, even though for us, we've gone further than that," Pitt told The Associated Press in an interview in November 2012. "But to concretize it in that way, it actually means more to me than I thought it would. It means a lot to our kids."
They have six children together, including three they adopted: 13-year-old Maddox, from Cambodia; 10-year-old Pax, from Vietnam; and 9-year-old Zahara, from Ethiopia. The couple's three biological children are 8-year-old Shiloh, and Knox and Vivienne, 6-year-old twins.
This is the second marriage for Pitt, who wed Jennifer Aniston in 2000. They divorced in 2005.
Jolie was previously married to British actor Jonny Lee Miller for three years in the late '90s and to Billy Bob Thornton for three years before divorcing in 2003.
Both Jolie and Pitt are prepping movies. Jolie's second directorial effort, the World War II odyssey "Unbroken," will be released in December. Pitt stars in the upcoming World War II drama "Fury," due out Oct. 17.
