"Brad and Angelina had a meeting with a top law firm in LA in December, where they worked out terms of a legal document similar to a prenup," an insider reveals exclusively to Life & Style. "The couple signed the document in early January. They agreed to share their money and assets and custody of their six children, all of whom would live with Angelina in the event of their parents' breakup."

But this doesn't mean they are ending their five-year relationship. "They didn't talk to the lawyer about splitting, nor was that ever mentioned at the meeting," the insider notes, adding that they were "snippy with each other" during the meeting. "Brad and Angelina aren't splitting right now," says a second insider close to the couple. "Will they be together forever as a couple? Probably not. It'll run its course, but I think they're fine -- for now."
