Jessica Alba
This one is sensationally hot.
Alba's body is enough to inspire fits of delirium, her eyes striking irresistibly and that bottom the stuff of dreams -- but she just cannot act.
A double Worst Actress nominee at the 2006 Razzies for her hideous, wooden performances in Into The Blue and Fantastic Four, Alba is a tragically bad actress.
The female Keanu Reeves, really.
