NCIS: Los Angeles star Eric Christian Olsen, 36, and his wife actress Sarah Wright, 29, welcomed their first child together -- Wyatt Oliver -- on Friday, August 16.
"I've been a part of some pretty incredible experiences in my life, but I've never been a part of something so surreal, so life affirming and so insanely beautiful as watching my son come into this world," he tells People. "It was this watershed moment where I knew that everything I valued before seems finite and temporary."
