Well, that was quick.

After a single day of waiting in limbo, Selma Blair has officially been sacked by 'Anger Management' after Charlie Sheen threw a hissyfit and threatened to quit if she wasn't cut.

TMZ reports that production company Lionsgate released a terse statement, like guilty parents who've just given their baby an entire ice cream cake to stop it from sobbing: "We are confirming that Selma Blair will not be returning to 'Anger Management' and we wish her the very best."

As we reported earlier, Charlie was miffed because Selma had informally complained to producers about his work ethic and tardiness -- throwing Charlie into full warlock mode and eventually leading to a pink slip.

This morning, Selma took it in stride, tweeting gracefully:

We're not happy about this, but it's probably for the best. After all, the last person who worked in bed with Charlie ended up in rehab.
