With the sad (though slightly ambiguous) news that Heidi and Seal were divorcing officially separating, our hopes were dashed once more that a seemingly non-jerky celebrity couple might actually make it. But seriously, they seemed pretty solid! And like people we'd want to be friends with! (We had the chance to see them at Heidi's famous Halloween bash this year and, to us, they truly seemed like two apes in love.) Even if S&H become another Hollywood casualty, we're still optimistic about these next fifteen duos on our list. If any of them split up, however, we're officially giving up on marriage. (Forgive us the hyperbole, but we're still feeling a little raw from Kim and Thurston's split.)
