Daniela Ruah is a mom!

The "NCIS: Los Angeles" actress, who's engaged to David Olsen, gave birth to their son on Dec. 30, People confirms.

She and Olsen -- a former Navy SEAL who is a stunt double for his little brother and Ruah's co-star Eric Christian Olsen -- named their baby boy River Isaac Ruah Olsen, the magazine reports.

"He's healthy and strong, which is all we could ask for," Ruah, 30, tells People. "We are so happy, so thankful and feel so blessed to have brought him into the world."
