Zoe Saldana's body "bent out of shape" after she gave birth.
The 'Guardians of the Galaxy' star welcomed twin boys, Cy and Bowie, in November last year with her husband Marco Perego and has spoken out about the "challenging experience" she went through during and after her pregnancy.
Writing on Facebook, she said: "As you all know, we welcomed twin boys last November. Yes, by far, the most amazing experience of my life, but also a very challenging experience when it pertains to my body...
"Your body changes dramatically, inside and out... In some cases more than others, your body experiences a kind of trauma through childbirth that is difficult to explain unless you've had that experience.
"My case was like that, everything from my thyroid to my platelets crashed. Thank God, we are all doing great now, but my body was really bent out of shape after the boys were born. (sic)"
The 36-year-old actress is working hard to get back into shape following the birth and is working alongside her friend and trainer Steve Moyer.
Alongside a photograph of herself in the gym, she added: "Bouncing back feels impossible, but I know it is important as a woman, and now a mommy, to not give up. I am determined to get my energy back and find balance for my body before these little guys start walking, and before I go back to work..... my clock is ticking! (sic)"
