"Psych" co-star Maggie Lawson is set to recur on the final season of CBS’ long-running comedy series "Two And A Half Men."

The storyline focuses on Walden (Ashton Kutcher) and Alan’s (Jon Cryer) decision to get married in order for Walden to adopt a child.

Lawson will play a social worker who will help the duo. This marks Lawson’s return to CBS where she starred in the comedy pilot "Save The Date" this past season.
