The Panama-born actress turned to alternative methods to start a family after learning she would never be able to become a natural mum.
She tells Cosmo for Latinas, "I couldn't carry a baby. It (surrogacy) taught me a lot to have to rely on someone else to carry my baby for me, because I'm such a private and self-sufficient person. It's the most intimate leap of faith and trust you can take."
Brewster and her husband, film producer Andrew Form, became parents last year (13) when their son Julian was born via surrogate.
