brian austin green wedding band episodic tnt 325 Brian Austin Green joins 'Anger Management' cast as Charlie Sheen's nemesis“Beverly Hills 90210″ alum Brian Austin Green has been upgraded from guest star to full-time regular on the FX comedy “Anger Management.”

Green first appeared as Sean, the nemesis of Charlie Goodson (Charlie Sheen), in the show’s premiere episode and recently returned in the episodes “Charlie Breaks Up with Kate” and “Charlie & the Secret Gigolo.”

“Anger Management” is going through a bit of a shake-up following the dramatic departure of co-star Selma Blair.

The series — Sheen’s follow-up to CBS hit “Two and a Half Men” — has also suffered from disappointing ratings after FX gave it a 90 episode order following a 10 episode trial run.

Green recently starred on the TBS comedy “Wedding Band,” which was canceled after a single season, and guest starred on ABC’s also canceled “Happy Endings.”
