Everyone was rooting for this couple, but it wasn't meant to be. After four years of marriage, it was over. Sources tell TMZ that the marriage fell apart because of a "third person."

We're told this is a strictly "amicable" divorce. In terms of courtroom conflicts, one source said, "It was over before it started." It seems the couple drafted a prenup before they were married and they have each agreed to walk away with what's theirs -- and no more.
