Selma Blair abruptly exits Charlie Sheen's "Anger Management"

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

In a statement Tuesday, producer Lionsgate said the actress won't be returning to the FX 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, as did FX.

The statement follows a report from TMZ, revealing that Blair and Sheen weren't getting along on the set and Sheen reportedly threatened to leave the series if his co-star stayed on the show. Insiders told The Hollywood Reporter that Blair criticized Sheen's work ethic, adding that Sheen -- who also serves as an executive producer -- sent Blair a text message, firing her from the series.

Filming resumed Tuesday without Blair on the set.

The sitcom represents Sheen's TV series comeback after he was fired from CBS' "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.
