Rosie Huntington-Whiteley caused a sensation

Replacing Megan Fox in the blockbuster Transformers franchise was no easy feat, but newcomer Rosie Huntington-Whiteley caused a sensation when she stepped out looking stunning in nearly every promotional stop.

From her sparkly silver turn in Naeem Khan in Berlin to the sexy plunging blue Burberry gown in London to the drop-dead stunning red Antonio Berardi dress in NYC, Rosie was dripping with movie-star glam as she crisscrossed the globe. (Her slouchy pink Michael Kors gown for Rio was also fab, and the only little hiccup was the sheer Gucci skirt in Moscow.)

RHW went casual chic in the Row's silk tank and slacks outside Regis & Kelly. The 24-year-old rocked a belted cream halter top and slacks by Michael Kors outside the David Letterman studios.

Her two black outfits (Brazil photo call on the left, Tonight Show on the right) weren't the best, but Rosie made up for it with the va-va-voom red Stella McCartney dress at the Berlin photo call.
