LOS ANGELES -- Selma Blair is making a sudden exit from the Charlie Sheen sitcom "Anger Management."

In a statement Tuesday, producer Lionsgate says the actress won't be returning to the comedy. The company says it wishes her "the very best" but has no further comment.

Blair's departure comes while the comedy is about halfway through completing its 90-episode order from FX.

The actress's publicist didn't immediately respond to a request for comment. Sheen's manager, Mark Burg, declined comment.

The sitcom represents Sheen's TV series comeback after he was fired from "Two and a Half Men" in 2011 after clashing with producers.

Sheen has an ownership stake in "Anger Management."

Blair played a therapist and colleague to Sheen's character on the show. Sunday is her 41st birthday.

"Anger Management" is broadcast in Canada on CTV and CTV Two.
