She’s a Teen Bride, singer and now she can add actress to her resume.
The Seinfeld star plays Donny Clay, a TV talk show host with a grudge against Dr. Phil, (and a bad wig) who has Courtney and Doug on as guests.

Check out Courtney’s video and tell us what you think about her acting chops in comments.
