Megan Fox is mere moments away from hitting the red carpet at the premiere of her film Jonah Hex (out in theaters this Friday) in a beautiful Armani Prive dress–and we got a sneak preview of the red-hot number. The custom-designed frock is made of bold red silk charmeuse. We love the plunging neckline and detail at the waist. Plus, the exaggerated shoulders and fitted long sleeves are so chic that they make us want to ask Giorgio to make another one...for us, of course. But this isn't Fox's first foray with the brand. In fact, she just debuted her second ad campaign as the face of Emporio Armani Underwear and Armani jeans. And, in September, Armani will be releasing a cinematic commercial with Megan to showcase the full collection. But if you can't wait until September, click below to see the ad.
