9. Jennifer Lopez
Worst Performances: The Wedding Planner (2001), Angel Eyes (2001), Gigli (2003), The Back-Up Plan (2010)
Back in 1997, Jennifer Lopez's performance in the emotional biopic Selena positioned her as one of Hollywood's most promising young actresses. One year later, alongside George Clooney in Out of Sight, the credible momentum was in full swing.
So what the hell happened to J. Lo the movie star? A series of bland rom-com scripts that have done little to help her once potentially top-notch dramatic skills mature. A lame byproduct of the movies she's picked (i.e, Maid in Manhattan, Gigli, and Monster-In-Law), Lopez unfortunately lessens her on-screen value in bad movies and does little to enhance the films.
