Talk about a transformation!

Rosie Huntington-Whiteley, who's donned several gorgeous gowns during her international promo tour for Transformers 3: Dark of the Moon, continued her run of knockout looks at the film's latest two premieres.

The Victoria's Secret model, 24, who replaced Megan Fox in the mega-successful movie franchise, went with a backless silver sequined short sleeve Naeem Khan gown on the red carpet in Berlin, Germany, which she accented with a thin silver belt, black nail polish and glam side-swept waves.

At the London premiere she went backless again, in a custom midnight blue Burberry gown, which also featured a plunging neckline (a big trend right now). Her hair was pulled back in a voluminous updo.

Last week Huntington-Whiteley made a sizzling debut in Moscow in a fuchsia pink Michael Kors draped dress with a sexy thigh-high slit followed by a Gucci gown, which featured a chartreuse one-shoulder top and a super sheer black skirt.
