Actress Zoe Saldana posted a photograph of herself in her old "Guardians of the Galaxy" costume to inspire other mothers to get back into shape.

"Holy S---! You guys, I had to share this, 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.

"@marvel and @jamesgunn don't be mad, I'm not showing anything that hasn't been seen before... besides, aren't we designing new stuff?. It pays off to work hard! I mean it mommies of the world, if I did it you can too (sic)," Saldana wrote.

The actress had insisted she would not diet after the twins were born but was struggling to avoid junk food at the weekends, reports femalefirst.co.uk.

"By Friday I'm anxious about what I will have to do over the weekend to avoid breaking my diet. I find myself dreading the awesome family feast gatherings, friends inviting me over for a 'wine and dine' on Saturdays, and then of course Sunday brunch," she said.

"So here is what I'm gonna start doing; I am going to remove the word 'diet' from my life. I am going to remind myself that it is not about losing weight, it is about being healthy, feeling healthy, for the rest of my life (sic)," Saldana added.
