Almost two years after announcing their split, Jennifer Garner is finally filing to divorce Ben Affleck, sources tell Us. The couple, who got together in 2003 and married in 2005, have three children together, ages 11, 8, and 4. "No matter what happens, Ben and Jen are committed to raising their family as one unit and will continue to do so as it has worked for them," a source says. New York points out that when Ben and Jen originally split, they gave the story to People, not Us, "so keep that in mind." A key piece of evidence used by Us to support its story? A source says Ben has finally moved out of the couple's formerly shared home. (More Jennifer Garner stories.)
