Lesson of the day: Don't argue with Charlie Sheen!
Selma Blair will not be returning to FX's "Anger Management" after a "heated battle" with Sheen, Lionsgate has confirmed.
"We are confirming that Selma Blair will not be returning to 'Anger Management' and we wish her the very best," the studio said in a statement.
Sheen no longer wanted to work with Blair, who plays his onscreen therapist, after she complained about his work ethic to the show's executives, according to our sources.
Earlier in the week, our source, who admitted things had "gotten ugly" between the two stars, said that Sheen doesn't have the exclusive right to fire anyone, but noted that the actor "certainly can make production impossible."
"Anger Management," which is currently shooting its second season, received a 90-episode order from FX after its first season, but has experienced a decline in the ratings in its sophomore outing.
Blair, who is known for her work in films such as Hellboy and Cruel Intentions, had been with the show since it first premiered in 2012, and while her character Kate was Sheen's character's therapist on the show, the two shared a "friends with benefits" relationship.
Production had recently resumed on "Anger Management" and Blair tweeted her co-star on June 10, saying, "Thanks for a great day back @charliesheen. You looked pretty darn handsome."
A rep for Blair did not immediately return E! News' request for comment.
