According to Entertainment Weekly, Jenny, a lesbian, moves to L.A. to pursue a career in acting and connect with her uncle Allan Harper (Jon Cryer).
"Men" producers had been looking for someone to play Charlie's daughter since late May. Tamblyn's role is expected help fill the void left by Angus T. Jones's departure from the show in a move that is probably related to his infamous anti-"Men" YouTube rant.
Tamblyn, 30, will appear in five episodes during the show's upcoming season, with the possibility to become a co-lead on the show.
