The actress will play Jenny, the late Charlie's illegitimate daughter on the upcoming 11th season of the CBS Show, a network representative told TheWrap.
She'll appear in five episodes and apparently share much of her father's favorite things, including women. The role may get bigger if the character works well for the show. The search for the actress to fill this role has been on since at least May.
Tamblyn's TV credits include "House," "Joan of Arcadia" and the daytime drama "General Hospital." As for films, she has appeared in "The Ring," "The Sisterhood of the Traveling Pants," and "Django Unchained."
In April, the comedy was renewed along with the news that Angus T. Jones, the titular "half" on the series, has been bumped down from series regular to a recurring role. Last year, the young actor had trashed the show in a religious video that went viral.
