How did Rosie Huntington-Whitely beat out fellow beauties Miranda Kerr, Bar Refaeli, Gemma Arterton and Brooklyn Decker for Megan Fox’s role in Transformers 3? Easy. She wore lingerie to her audition!

The Victoria’s Secret model made a crafty clothing choice when director Michael Bay called her in to do a trial love scene with leading man Shia LaBeouf. “Rosie wore a white, see-through lingerie top and panties. Shia was there to run lines with her,” an on-set source tells HollywoodLife.com exclusively. “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.”

Now that the 23-year-old English beauty has the role, what can she do to avoid making the same mistakes as 24-year-old Megan? The answer is pretty simple: BE NICE.

“No matter what people spin or say, Megan Fox was fired. 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,” our insider reveals. “Michael [Bay] accepted her behavior but didn’t like the fact she would refuse to go to events and other things that Michael thought would help in the promotion of the films. They definitely didn’t get along, but basically the only person who CAN get along with him is Shia!”

And now Shia will be getting along VERY well with Rosie. Sorry, Megan. Your loss is an underwear model’s gain!
