Actress and country singer Laura Bell Bundy is on a major roll. She recently signed a new record deal and released a new single, and now the entertainer has signed on as a series regular in 'Anger Management,' opposite Charlie Sheen.

According to the Hollywood Reporter, Lionsgate, which produces the FX comedy, announced the new casting on Monday (Aug. 5). Bundy will play Sheen's new sex study research partner, Dr. Jordan Denby.

FX describes the character as "a brilliant psychologist whose recent divorce, fondness for alcohol and wild mood swings turn Charlie's life into an emotional roller-coaster."

The Tony nominee is replacing Selma Blair as the series' female lead. Blair was fired from the show in June after clashing with Sheen.

Bundy's past credits include 'Legally Blonde: The Musical' on Broadway, as well as roles on 'How I Met Your Mother' and a recurring role on 'Hart of Dixie.'

Bundy is scheduled to begin filming her new part this week. She has recently been on the road with Rascal Flatts, promoting her new single with Colt Ford, 'Two Step.' It is the first single from an album she is expected to release under her newly-inked deal with Big Machine Label Group.
