Fitting in! Zoe Saldana probably questioned whether she was ever going to get her body back after giving birth to twins a little over a year ago. Well, she's questioning no more.

The actress took to Instagram on Dec. 10 to show off her bod while slipping into an old "Guardians of the Galaxy" costume, one that she wore before becoming pregnant with little Cy Aridio and Bowie Ezio Perego-Saldana.

Even Zoe seems surprised at the progress she's made.

"Holy S---! You guys, I had to share this," she captioned the image that shows her in the tight outfit, her hands on her hips. "This is one of the old #guardiansofthegalaxy costumes that I wore back in 2013. After twins I can't believe I was able to slip into this."

She went on to apologize to Marvel and the creator of the film for showing off the outfit before encouraging them to design to outfits for the already-announced 2017 sequel.

Really though, the Instagram post wasn't about the movie. It was about Zoe and her post-baby body, something she worked hard for. Over the past year she's often shared pictures and videos of herself working out on social media. Now, mama can rest a bit easier knowing that it was all worth it.

"It pays off to work hard!," she wrote of the Instagram snap. "I mean it mommies of the world, if I did it you can too."
