Tamblyn will play Jenny, who has moved to Los Angeles to pursue acting and connect with what's left of her family. She likes everything her dad liked, including women. Tamblyn will recur in at least five episodes, with an option to join the CBS comedy as a series regular.
In April, CBS announced that the series was renewed for an 11th season, but that original cast member Angus T. Jones wouldn't be returning full-time. Original cast member Charlie Sheen was fired from the show in March of 2011 and was eventually replaced by Ashton Kutcher.
Two and a Half Men returns Thursday, Sept. 26 at 9:30/8:30c on CBS.
