Fired or written off? Three months after the fact, Charlie Sheen addressed his Anger Management costar Selma Blair's controversial exit from the show during an appearance on The Tonight Show with Jay Leno Wednesday, Sept. 11.

In June, Lionsgate, which produces the FX sitcom, said in a statement, "We are confirming that Selma Blair will not be returning to Anger Management and we wish her the very best." At the time, Deadline claimed that Sheen, 48, fired Blair, 41, in an expletive-filled text after Blair reportedly took issue with the former Two and a Half Men star's on-set behavior.

Sheen, however, has a difference version of the story.

"One of our primary characters, Selma Blair, who played Kate, was written out because [the show] was not about our relationship, and the problem was too many people were still excited about the Two and a Half [Men] character and thinking the Anger Management character was a little dull," Sheen explained to Jay Leno. "So, um, that is not the case anymore."

"She leaves and [my character starts] circling the drain," added the actor, whose struggles with drug and alcohol abuse are well-known. "So it's really fun to watch and hella fun to play."

"Where do you draw from [for] that?" Leno quipped. "Where do you draw from the experience for that?" 

"It's a mystery," Sheen joked. "It just falls out of the sky. It's crazy, it's amazing."

In August, Lionsgate revealed that Laura Bell Bundy would be joining the cast to play Dr. Jordan Denby, the "new sex-study research partner" of Sheen's character, an anger management therapist. She's "a brilliant psychologist whose recent divorce, fondness for alcohol and wild mood swings turn Charlie's life into an emotional roller coaster."
