Fox has topped the list of worst actresses by film website Moviefone.com for her role in action sequel Transformers: Revenge of the Fallen, narrowly beating out Beyonce Knowles for her performance in thriller Obsessed and Hilary Swank in Amelia.
But the 23 year old can console herself after landing the title of sexiest actress in the same poll, seeing off competition form Star Trek's Zoe Saldana and Sandra Bullock.
Fox's Transformers follow-up also divided voters, being named both worst movie of the year and best action movie.
Twilight's vampires and werewolves also proved popular, with British heart-throb Robert Pattinson scooping the title of sexiest male star and Taylor Lautner being named male breakout star of the year. The Twilight Saga: New Moon was named best film ahead of Avatar and The Hangover, and the bloodsucker movie was also crowned best chick flick.
