Details of Brad Pitt and Angelina Jolie Pitt's Last Months of Marriage

Jolie Pitt filed for divorce on Monday, citing irreconcilable differences.

The celebrity power couple started dating after meeting on the set of their 2005 movie "Mr. and Mrs. Smith" and now have six children together. Jolie Pitt has filed for physical custody of children -- Maddox, Pax, Zahara, Shiloh, and twins Knox and Vivienne.

One of the last photos taken of the couple in public was on July 4 as they were leaving Gelson's Market in Los Feliz, California. The last time they were pictured together was reportedly on July 12, when the family celebrated Knox's eighth birthday at The Griddle Cafe in West Hollywood, according to TMZ.

The last time Pitt was last photographed in public was at Los Angeles International Airport on July 24.

Last year, the couple starred together in "By the Sea," in which they played a glamorous couple whose marriage was on the rocks. The film was directed by Jolie Pitt. In a 2014 interview with The Associated Press, Jolie Pitt said it was cathartic to play a couple with marital problems.

"It almost makes you get past those issues because you can laugh at them," she told The AP. "You do a film about bad marriage and you witness that behavior. You study it, you let it out, you attack each other and then you just want to hold each other and make sure you never behave that way."

The couple reportedly celebrated their second anniversary in August with a "low-key date night" at the Beverly Hills Hotel, according to Us Weekly.
