So Zoe Saldana is in for her biggest adventure yet!

On Saturday, the 38-year-old actress announced that she and husband Marco Perego are now parents three times over.

“Marco and I are elated to share the news of the birth of our son Zen,” Saldana wrote in the Instagram caption.

Cy and Bowie, Saldana and Perego’s 2-year-old twins, are also pictured.

Saldana has been an open book on the challenges of motherhood, from the harrowing premature birth of the twins to the struggles of getting her body back.

Last year, Saldana also revealed that she suffers from an autoimmune disease called Hashimoto’s thyroiditis, which led her to take ownership of her lifestyle to improve her health.
