Eric Christian Olsen of 'NCIS: Los Angeles' and his actress wife, Sarah Wright, have been parents since Aug. 16, but they just made the news public today -- so belated congratulations are in order to them for welcoming brand-new baby Wyatt Oliver!

"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," Olsen told People of the joyous event.

He then got deep on the magazine, explaining, "It was this watershed moment where I knew that everything I valued before seems finite and temporary ... I can only take stock in how lucky I am to have this amazing, powerful, woman in my life, and a beautiful new son."

Olsen revealed that his wife wanted an at home, natural birth and that she was in labor for an anxious 17 hours. Yikes.

This is the couple's first child together after tying the knot in June 2012.
