Scarlett Johansson is obviously in terrific shape for 'Iron Man 2' and Entertainment Tonight has a behind-the-scenes look at how she got her catsuit-ready body.

"I don't think I've ever worn anything like it before," she said. "I mean, it's a unitard ... a sexy unitard."

Scarlett's costars had no problem with the unitard.

"I saw the costume when we were doing wardrobe tests, and I was just like, 'Oh my god, this is just not fair,'" said Robert Downey Jr.

"I think Black Widow's gonna bring, like, tongues hanging, drooling toward her," said Samuel L. Jackson. "Plus, she's kicking so much ass."
