"Transformers: Dark of the Moon": Rosie Huntington-Whiteley's premiere looks

(CBS) - Rosie Huntington-Whitely is on the publicity trail for her first film "Transformers: Dark of the Moon," and the Hollywood newcomer has undertaken a lot of wardrobe changes on each stop of the way.

Joined with director Michael Bay and fellow castmates, the British model and actress traveled through Russia and Europe last week, attending three red carpet premieres and two photo calls.

At the Moscow premiere, the 24-year-old, who replaced Megan Fox in the film, stepped out in a Gucci gown, which featured a chartreuse one-shoulder top and sheer black skirt. Earlier in the day, she sported a bright fuchsia Michael Kors draped dress with a thigh-high slit.

The Berlin premiere and photo call also called for two separate showtopping outfits. A low cut, long-sleeved maroon frock paired with tan Christian Louboutin pumps were her picks for the photo call. She later went for a backless silver and sequined short-sleeve gown by Naeem Khan for the red carpet premiere.

A stop in the U.K. was the last leg in Huntington-Whiteley's European promotional tour.

At the premiere in London, she donned another blackless design, this time from Burberry. She paired the sapphire evening gown with an updo and simple jewelry.

Tonight, Huntington-Whiteley is expected to step out in yet another glamorous look for the New York red carpet premiere.

"Transformers: Dark of the Moon," which is the third chapter of the popular franchise, is due in theaters Wednesday.
