Rosie Huntington-Whiteley has revealed that people often expect her to be mean.
The 24-year-old British model, who replaced Megan Fox in the upcoming Transformers: Dark Of The Moon film, admitted people can misjudge her.
"People always tell me, 'Gosh, you're so nice!' Like they expect me to be a huge b****!" she told US Women's Health.
Rosie - who plays Carly, girlfriend of Sam Witwicky (Shia LaBeouf) in the third Transformers outing - admitted her film debut wasn't glamorous.
"Shia made it clear this wasn't just about becoming a movie star. The shooting schedule was going to be gruelling," she recalled.
"You're in the sun all day long...it was dirty and smelly on set. It was like boot camp."
