Jennifer Lopez posted photos showing her in a black "revenge dress" during her London promotional events for her new movie.

For the occasion, Lopez decided to wear a daring, silver Tamara Ralph gown featuring head-to-toe slits on the side held together with large black bows. While stopping at the media tent to answer some press questions, Lopez told People that she wasn't sure she'd wear the nearly-naked gown while walking the red carpet.

The "Selena" actress stunned at the LA premiere of "Wicked" Saturday night, wearing a skin-baring, beaded brown and cream Zuhair Murad gown.
