That noise you just heard was the heads of celebrity tabloid editors' heads exploding in unison at the news that Brad Pitt finally put a ring on it and proposed to Angelina Jolie.

Rumors of an engagement began to swirl when Jolie was spotted at a private viewing at the Los Angeles County Museum of Art's Chinese galleries on Wednesday rocking quite a sparkler on her ring finger. Pitt's manager Cynthia Pett-Dante confirmed the engagement to People, saying, "It is a promise for the future and their kids are very happy."

The pair have been together for seven years and have six children. Their love story has been documented like crazy by the tabloids, but in honor of their long-overdue engagement, we decided to take a look back at the highlights of their relationship to show you how they got from meeting on a movie set to preparing to walk down the aisle.

And it means something to me, too, to make that kind of commitment."
