Angelina Jolie & Brad Pitt: A Timeline of Their Relationship From 'Mr. & Mrs. Smith' to Divorce

After two years of marriage, Angelina Jolie has filed for divorce, ET can confirm.

This is undoubtedly the celebrity split of the decade.

After two years of marriage, Angelina Jolie has filed for divorce from Brad Pitt. Court documents obtained by ET show that 41-year-old Jolie separated from her husband, 52, on Sept. 15, 2016, and that the actress is asking for physical custody of their six children -- Maddox, Shiloh, Pax, Zahara, and twins Vivienne and Knox.

This certainly doesn't bode well for love (or our clearly cursed list of fave celeb couples), and it brings up a lot of reflection on the time the two -- who basically seemed like a unit at this point -- spent together, from their movie-set meeting, to their long overdue matrimony, to their shocking split.

Here are some key moments in Brangelina's romance.

May 2004: Meeting on Mr. & Mrs Smith

20th Century Fox

Pitt met Jolie on the set of the action-comedy film, while the actor was still married to Jennifer Aniston.

Naturally, this soon created a lot of controversy, as their obvious onscreen chemistry led many to speculate that this is where things started to go wrong for Pitt and his Friends star wife.

While denying any infidelity, the Ocean's Eleven star did later admit in a 2008 Rolling Stone interview that this is his favorite film of Jolie's, adding, "Because I fell in love."

Jolie also revealed to Vogue in 2006 that the film was clearly the beginning of something serious.

"It took until, really, the end of the shoot for us, I think, to realize that it might mean something more than we'd earlier allowed ourselves to believe," she said at the time. "And both knowing that the reality of that was a big thing, something that was going to take a lot of serious consideration."
