Rosie Huntington-Whiteley Thought She Was up for Robot Role In Transformers 3

Rosie the Robot?

It was too her great surprise that racktastic and rumpalicious UK model Rosie Huntington-Whiteley learned that she was going to be replacing notorious skin-flint Megan Fox in the upcoming summer action flick Transformers 3.

Megan's obstinate refusal to flash flesh (probably not even for her gynecologist) has sent her acting career into a freefall at terminal velocity and got her kicked off the big-budget sure-to-be-blockbuster last year.

But this news escaped Rosie's attention. And went she went to audition for a part in Transformers 3, she thought she was replacing Megatron, not Megan Fox.

So when she was called in by producers to see if she was hotter than Fox and showed up doing her best impression of a giant space robot, she understandably got a distorted picture of the audition.

"I went to the casting unaware they were looking for a new female lead. We were told it was for a 'nemesis' role. I left thinking I was awful. The next day I was offered the lead!

I met Shia Lebeouf that evening and within three weeks I was shooting my first scenes."

The only way this story could have ended any better is if she said she were shooting 3-D full-frontal scenes like Charlotte Ross in Drive Angry or Betsy Rue in My Bloody Valentine.

That truly would be trance-forming. And tent-in-the-pants-forming.
