Megan Fox solidified her bombshell status with Michael Bay's Transformers franchise, but when the third installment — and one of this Summer's most anticipated blockbusters — opens June 29, Shia LaBeouf will have a new leading lady at his side.

Will you choose former Victoria's Secret model Rosie's English-rose beauty, or Megan's dark, just-a-little-dangerous sexiness?
