The American Idol judge wore a typically daring dress -- a custom Zuhair Murad couture gown with a plunging neckline and cut-out sleeves -- that many watchers feared would expose more than Lopez bargained for.
Thankfully, Lopez (alongside Diaz, wearing a figure-hugging, strapless Gucci gown) did avoid a wardrobe malfunction -- although much of Twitter speculated otherwise.
Still, she didn't leave the stage totally unscathed. Presenting the first trophy, she and Diaz, 39, tried to pull off a joke. The sexy twosome turned their backs to the stage and looked over their shoulders with a knowing wink.
