ROSIE Huntington-Whitely is having to work hard to ready herself for Transformers 3.

The British model — who replaces Megan Fox as Shia LaBeouf‘s interest in the movie franchise — has been put on a rigorous diet and exercise program ahead of filming in LA later this summer.

“Rosie clearly has the looks to replace Megan but she isn’t being allowed an easy ride in preparing herself for what is a physically demanding role,” reveals a source close to the 24-year-old.

“She is working with two different personal trainers and is undergoing firearms and stunt training. She’s really being put through her paces.”

Recent reports claimed Rosie turned up to her Transformers audition wearing see-through panties!

“Rosie wore a white, see-through lingerie top and panties,” a source said.

“Shia was there to run lines with her. It was a formality, she had the part, but she had to meet Shia to see if they gelled.

“Having her in as little clothing as possible was just the icing on the cake. When she walked down a staircase in that outfit — wow.”

“No matter what people spin or say, Megan Fox was fired,” the source added.

“She was very bitchy on the first two films; she always had an attitude. So it wasn’t a surprise that she got booted from the third film.”
