The two of them welcomed their new arrival quietly in Los Angeles. They're apparently already loving their new roles as mom and dad.
"They are so excited to be first-time parents," an insider told Us of the actress and her hubby. "It was a very easy pregnancy and birth."
"Naya was born to be a mother and is doing really great so far," the source added. "And Ryan has amazing paternal instincts and has been waiting on them both hand and foot."
Naya and her husband of one year first announced her pregnancy via Instagram this past April. "Surprise! We're having a baby! Ryan and I feel so blessed and can't wait to welcome the newest member of our family," she wrote in the post, on top of an adorable throwback photo of herself and her hubby as kids.
The new parents married in a destination wedding in Cabo San Lucas, Mexico, in July 2014, three months after Naya ended her engagement to rapper Big Sean.
