Zoe Saldana is thankful for her youngest son, Zen.
The Guardians of the Galaxy star celebrated her baby boy's first birthday on Tuesday by penning a heartfelt note and sharing it on Instagram.
"Happy Birthday Zen Anton Hilario. You came into our lives in the most 'zen' way, and today you still continue to be our little Yogi baby," Saldana began. "Your Joie de Vie keeps all of us wrapped around your little finger. Your brothers are the most blessed big brothers in the world."
"Thank you for choosing us to guide you through your first life years, we are honored. Zen Zen, the world will be as worthy of you as any child in this world," she continued. "We will work towards that purpose every day. You are seen, loved, respected and protected by everyone that knows you. God Bless you baby boy!"
Saldana and her husband, Marco Perego, are also parents to 3-year-old twins, Cy and Bowie. The couple announced the arrival of baby Zen in February of this year with a sweet family pic shared on Instagram.
"Marco and I are elated to share the news of the the birth of our son Zen. We couldn’t feel more blessed with the new addition to our family. #threeboys... oh boy!," the actress wrote on Feb. 18.
The couple has always maintained a private personal life and has not opened up about how Zen was conceived since the news of his arrival.
In an interview with People earlier this year, Saldana opened up about protecting her children's privacy and how she was not quite ready to share the story of their family's new addition.
"This is something we’re being very meticulous about because of the process of how we completed our family," Saldana explained. "When we’re there, when the time comes and our third baby is a little older, and all the forces that helped us have him with us are comfortable, then we will share it because we know it would be very positive and inspiring to many families that are looking to complete themselves and are not able to do it in the conventional way."
"Seeking alternative ways to start a family should be encouraged, should be empowered and I think we should spread that education, that information out there, when the time is right," she added.
ET caught up with Saldana in April, where she gushed about her three boys and revealed if she was trying for a baby girl.
