The 24-year-old Victoria's Secret angel attended multiple events at the 33rd Moscow International Film Festival and each time pushed the style envelope, always looking effortlessly glamorous and sexy.
She first attended the photocall for the film with cast and crew wearing a fuchsia Michael Kors draped gown from designer's Spring 2011 collection. The asymmetrical one shoulder gown had a thigh high slit and a slash neck.
Opting for a minimalist look, she accessorized with pointy baby pink pumps.
Her blond locks tantalizingly framed her face, with ends curled for that extra volume. With a pretty face like hers and a fresh face look as the chosen style, there was little need for makeup.
She wore shimmering pink lipstick and glittering eyeshadow used as liner.
Next, for the premiere of the film, the British supermodel wore a yellow and sheer black Gucci Fall 2011 gown. The one shoulder gown had a ruffled top accented with a chunky floral applique, and an all through sheer skirt that teased her hot bikini ready legs.
Her side swept hair and a plum pout made the styling intolerably tormenting.
The third event of Rosie's ultra glam day was a free outdoor concert by American rock band Linkin Park in honor of the film's release at Vasilyevsky Spusk, Red Square, Moscow; she attended the event aptly dressed in skinny jeans, boots and a blazer paired with stick straight hair.
Linkin Park provided two singles for the Transformer series, What I've Done for the first Transformers, and the underwhelming New Divide for Transformers: Revenge of the Fallen.
She was joined at all the events by her equally hot co-stars Shia LaBeouf, Patrick Dempsey, Tyrese Gibson, John Malkovich and Josh Duhamel. Director Michael Bay was by her side as well.
