Scarlett Johansson is giving the skinny on how she's slimming down for her new role as Black Widow in 'Iron Man 2,' denying the rumors that she's been on a crash diet. In a blog written for the Huffington Post, the actress says she's taken her workout to a whole other level. "I've come to this conclusion: chin ups are near impossible and lunges suck," she writes. "There is no magic wand to wave over oneself to look good in a latex cat suit. Eating healthy and getting fit is about commitment, determination, consistency and the dedication to self-preservation." Scarlett also used the blog to clear up rumors of her dropping 14 pounds. "If I were to lose 14 pounds, I'd have to part with both arms. And a foot. I'm frustrated with the irresponsibility of tabloid media who sell the public ideas about what we should look like and how we should get there." She continues by saying she feels "the press should be held accountable for the false ideals they sell to their readers regarding body image." The actress is currently the face of Dolce & Gabbana's makeup line. She can also be seen in her "cat suit" when 'Iron Man 2' comes to theaters in May of next year.
