Look at that stomach!
Hilary Duff graces the May Issue of Shape Magazine -- and we can't stop staring at the star's super shredded physique.
The 27-year-old showed off her impressive cover to her Twitter followers on Wednesday, getting her fans in a frenzy over the image.
"I'm so excited about this cover! Thanks @Shape_Magazine for a fun shoot! Go pick up your May copy on Tuesday!!!," she said of the post.
In the shot, the former Disney darling shows off her tight tummy in a ruffled bikini top, a pink cardigan and a pair of tiny jean shorts.
The mag promises to reveal "11 simple tricks that keep her fit" -- and with that body, who wouldn't want to know her secret?!
The mom of son Luca, 3, hasn't been shy about showing off all her hard work in the gym. Just last month, the "Sparks" singer made headlines for sharing a super revealing bikini pic with her Instagram followers.
"Hey #moms #westillgotit ❤️ #loveyourbod," she captioned the sexy snap.
So what prompted the newly single star's bold post?
"You now what, I've never done anything like that before. My Instagram page is pretty tame. And I had spent all weekend in a bikini and I was feeling pretty good," she said recently on the Ellen DeGeneres Show. "I'm like, 'I'm just so proud of my body and what it's done for me, it gave me the most beautiful little boy and I feel strong and powerful and I wanted to inspire other women."
