Take The First Wives Club, subtract two husbands, add in Kate Upton’s jiggling assets, and you more or less have the premise for The Other Woman, about how Cameron Diaz became friends with all the other women her boyfriend (Nikolaj Coster-Waldau, a.k.a. Jamie Lannister) is seeing. That includes his wife, played by Leslie Mann, who really cannot catch a break from movie husbands or scripts. Anyway, high jinks and questionable beach hats ensue. Do they all sing at the end? Would you be excited if they did?
