Scarlett Johansson has tough advice for anyone wanting to stay in great shape.
"It's a lot of hard work and discipline, as I'm sure you know," Johansson told ET's Cameron Mathison while promoting her upcoming film, Ghost in the Shell.
"It's a lifestyle that starts at the gym in the morning and then I fight my way through the day."
Johansson's flawless figure is put on full display in Ghost in the Shell, in which she plays a special ops, one-of-a-kind cyborg hybrid who leads a taskforce in taking down a nefarious computer hacker.
The 32-year-old actress spends most of the film in a skin-tight latex unitard -- a far cry from the bulky suits worn by Johansson’s male Marvel co-stars, who play heroes like Iron Man and Captain America.
"I'm watching it thinking about all these male superheroes that get the padding and they get all the things that cover up, and I'm like, 'Man, not you.'" Mathison pointed out.
"Not me, man," Johansson said. "Bring it, Chris Evans. Bring it!"
While on screen she battles some of the most dangerous criminals and terrorists, in real life, Johansson shows a softer side.
The four-time Golden Globe nominee shares a two-year-old daughter, Rose, with her journalist husband, Romain Dauriac.
"I sing all day, probably much to her annoyance, and sometimes it's songs she doesn't want to hear, so she'll just go, 'No, not that one.'" Scarlett said. "I'm like a jukebox."
Scarlett admits she's not the best at carrying a tune, but she said her daughter shows promise.
"She's really good at singing 'Let It Go,'" Johansson said. "She's got a good ear."
Ghost in the Shell opens March 31.
