Ménica Cruz, the sister of Penélope Cruz, is pregnant.
“I’m going to be a mom!” she wrote. “I have achieved the dream of my lifetime.”
Cruz, who is an actor and dancer, also expressed her gratitude to “those anonymous donors that help so many women, like me, to achieve their dreams.”
Her decision to publicly share her road to motherhood, she wrote, comes from her desire to help other women who want to do the same.
