NCIS: Los Angeles star Eric Christian Olsen is set to become a first-time father.

The actor, who plays Detective Marty Deeks on the hit crime series, has announced that he and his wife Sarah Wright will welcome a baby boy in August (13).

He tells, "When they handed me the 3D sonogram and I saw Sarah’s perfect lips and that little Norwegian nose just like mine, I was overcome with a sense of clarity in the world that I can only imagine is beginning of fatherhood. We’re so excited and can’t wait to meet him."

The couple exchanged vows at a ranch near Jackson Hole, Wyoming last June (12).
