In August it was announced that Ali Fedotowsky and Roberto Martinez would tie the knot next summer, but there may not be a wedding at all. There's trouble in the relationship and a breakup might be right around the corner.

Sources claim their relationship has been "tumultuous since day one" and they're either "extremely happy or they can't stand each other." Another source claims they bring out the worst in each other.

A friend said after a nasty fight, "Ali was in tears. She's miserable in the relationship and he is too."

That's not good. You don't need a crystal ball to predict these two going separate ways by the end of the year, if not sooner.
