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, repped by Alchemy Entertainment, Gersh and attorney Michael Schenkman, 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.
