The fit star, 33, looked stunning in a black and white two-piece bikini, which flashed her signature abs and fit backside.
On the July issue of British GQ, she posed in a simple one-piece, and in May, she sported a pool-soaked white bikini on the cover of Entertainment Weekly.
The Sin City actress told British GQ that women need to remember to enhance what is good about their body.
“I have to enhance what I like about my body and my stomach is good,” she said. “My legs I’m not as excited about all the time, but I wouldn’t cover up my stomach. That’s what women do. Enhance what we’ve got.”
The star also went on to talk about her role in 'Sin City,' and how she's changed over the course of the first movie.
"I feel much more grounded, much more comfortable, much more saucy. Then I was a girl, I was timid, I was afraid, I was so insecure and now I'm a woman and it's different… I'm more uninhibited."
"There's more of me and I do more than I did in the first one. I have a bit more of a character arc in this one. There's more dancing, but the dancing's really connected to the story. Nancy's a bit of an alcoholic and a bit of a mess and she's depressed and angry. The dances in the movie reflects where she's at."
Though the star looks incredible, she admitted to US Weekly that continuing to keep herself fit is not her idea of a fun time, saying that she "dreads working out."
“What is really hard—squats!” she said. “[And] plyometrics are really hard for me. They’re exhausting. And I’m really bad at push-ups.”
