Hollywood actress Scarlett Johansson enjoyed wearing her skin-tight superhero suit so much in Iron Man 2 that she wanted to keep it home. The actress who plays undercover spy Natasha Romanoff, also known as Black Widow, in the comic book sequel, had to work out hard to fit into the costume but got so much pleasure from wearing it she didn't ever want to take it off, reports femalefirst.co.uk.

"One of the biggest motivators was when I first saw the Lycra catsuit. I was like, 'If I gotta get into that thing, I better start now.' The challenge was to get in the suit and believe it," she said.

"I wish I could have kept it afterwards but unfortunately it's the property of Marvel so, after I took it off for the final time, I said, 'Ta-ta for now. I love you! Hopefully I'll see you in the future!'," she added.

The 25-year-old beauty took on a complex exercise regime and diet plan in order to squeeze into the skin-tight outfit but admitted it had been an "empowering experience". "I did a lot of weight training, mixed martial arts and hand-to-hand combat. When you're working out that much you also have to feed your new body, so you eat in a different way, very clean, lots of omelette, turkey, stuff like that," she said.

"It's been an empowering experience which made me feel much stronger than I've ever felt before just because I built up so much strength," she added.
