Selma Blair may have left Charlie Sheen's FX show "Anger Management," but it wasn't over anger issues, says Sheen.

During a visit to "The Tonight Show" Wednesday night, Sheen addressed Blair's controversial ouster, but dodged addressing whether there was any friction between him and his co-star, as had been rumored at the time.

"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 told Jay Leno.

"So, um, that is not the case anymore," he added, suggesting that his therapist character was no longer boring. "She leaves, and I start circling the drain. It's really fun to watch and hella fun to play."

Blair left the show in June, midway through its second season. At the time, E! News said that Sheen didn't want to work with Blair because she complained about his work ethic to executives, and Deadline reported that he'd fired her with an expletive-filled text. 

Leno wondered just how will Sheen know how to play a character who is "circling the drain" — an almost rhetorical question, given the actor's well-known issues with drug and alcohol abuse. 

"It's a mystery," laughed Sheen about his inspiration. "It just falls out of the sky. It's crazy, it's amazing."

With Blair gone, Laura Bell Bundy has joined the show as Sheen's new research partner, and Brian Austin Green has been made a regular. 

Said Sheen, they're now calling the show, "Anger Management 2.0."
