Rosie Huntington Whiteley breathtaking in barely there blue gown at London premiere of Transformers 3

She's had enough practice as her years as a model on the catwalk - and it seems that Rosie Huntington-Whiteley is turning her movie red carpet outings into something of an art form.
The ravishing Victoria's Secret model, 24, had the crowds gasping at the London screening of her debut film Transformers 3: Dark Of The Moon tonight when she turned up in a risqué midnight blue gown.

The backless satin dress, custom made for her by Burberry, was slashed almost to her navel with only modest drapes of material over her breasts to keep her decent.

 Feeling blue: Rosie Huntington-Whiteley looked stunning in a sapphire blue gown that just about kept her decent at the London screening of her new movie Transformers 3: Dark Of The Moon at the IMAX cinema in Waterloo tonigh

 

 

Sapphire and steel: The model looked icily cool in her stunning frock on the blue carpet at the bash

 

Keeping it together: Rosie had some toupé tape to keep herself decent as she posed with the movie's 

director Michael Bay

Yet the star, who had her hair in a chic up-do, managed to look classy at the same time - quite a feat. 

It appears that some judiciously-placed toupé tape on her top half was most definitely keeping the star from revealing more of her curves than she intended.

Just last night, she looked equally incredible in a sparkling silver gown for the German premiere of her first ever movie in Berlin. 

 

 

 Back to the future: Rosie, who looked sensational in the sapphire gown, is hoping to do more acting as well as continue with her modelling
