The "Legally Blonde: The Musical" star will play Sheen's new sex study research partner, Dr Jordan Denby, on the FX comedy, reported Aceshowbiz.
In a statement, the producers describes Bundy's "Anger Management" character as "a brilliant psychologist whose recent divorce, fondness for alcohol and wild mood swings turn Charlie's life into an emotional roller coaster."
Blair was dismissed from "Anger Management" in June via text message after a reported disagreement with Sheen.
