It looks like Charlie Sheen has found his foil…

The 47-year-old part-Spanish actor has named former 90210 star Brian Austin Green as his character’s permanent nemesis on FX’s Anger Management.

Green was mad a series regular after a memorable guest stint as Charlie Goodson’s (Sheen) archfoe Sean.

Green’s character was introduced in the series’ first episode last year and recently was brought back for two more episodes from Anger Management‘s 90-episode back order.

He recently starred on the TBS dramedy The Wedding Band and had a recurring on ABC’s Happy Endings as Casey Wilson’s love interest.

Meanwhile, Anger Management also is looking for a new female addition following the exit of co-star Selma Blair.

Casting is underway for the new “sexy” role, which will likely be introduced on a recurring basis.
