Rosie Huntington-Whiteley looked crazily hot in a backless sapphire Burberry gown with a plunging neckline at the UK premiere of Transformers: Dark of the Moon on Sunday, June 26 at BFI IMAX in London. The 24-year-old English model and debutant actress chose a home based designer for the home turf appeareance to plug her film. She has been the Burberry face since 2009. 
The custom halter gown with a soft train had sparkling shoulder straps that ran all the way down through the center of her bare back, and a deep plunging V neckline that slashed to the naval.
She accessorized with just a pair of small stud earrings. A small heart tattoo adorned the outer edge of her right wrist. 
Her blond hair was styled in a tousled French roll with a swept back bouffant top.
She wore Burberry makeup - berry pink lipstick and accented her bluish Grey eyes with metallic eye shadow, using smudged kohl liner on lids.
Rosie, a Victoria's Secret Angel, combined sartorial sublimity with supermodel poise in the daring, wardrobe malfunction prone attire, looking as elegant as sexy when posing for cameras. Malkovich and Josh Duhamel - and its director, Michael Bay, are on a globe straddling tour to promote the film, which they kicked off with its world premiere at the Moscow Film Festival on June 23.
