"I need to take a break I need to, like, go away," she told ET's Kevin Frazier at the film's Los Angeles premiere. "I'm sure everybody is tired of seeing me. This has been like a very intense tour. People are loving the film, which is so great, but at the same time like I need to like go and chill out and disappear for a second."
Two people who will be excited for Theron to take some time off are her children, Jackson and August.
"I was away for a week, and they know I was away for work," she explained of her kids. "They saw us getting ready tonight to come to this, and I don't even think they put together it's for the movie or anything like that. They were just like, 'Don't go!'"
Theron looked glam at the premiere, stepping out in a black Dior bra and skirt topped a sheer fringed shirt, which she accessorized with a chunky choker, bangle and cocktail rings and black pointed booties. But in Atomic Blonde, she wasn't afraid to get dirty and wail on the film's buff stunt men.
"That was not because I was trying to be cool or badass," she revealed. "They allowed me to do things that anybody else probably would, you know, go home and cry about, and they would just get up and be like, 'That was great, do that again. That was amazing'… I can't give them enough credit for how good they make me look in this film.
