Zoe Saldana "cried every day" when she returned to work after having twins.
The Star Trek star admits she got emotional when she first went back to a film set following the birth of her 20-month-old kids Cy and Bowie.
She said: "The first week back at work, I think I cried every day in my trailer. But I remember as soon as they would tell me 'We're ready for you on set,' I would still skip to set. I love what I do. You do need to rest, you do need to have a moment to yourself, but right now this is my life as I know it.
"They're 20 months old, and they're starting to feel my absence. They still don't really have an accurate concept of time, but they're becoming a little anxious. And that's when you ask people, you ask a therapist 'Is this normal?' You read books, you go on Google ... But I always explain to them that I come and I go, but Mama has to work. I also make sure that they see me happy when they come visit me at work - they need me to lead by example."
