Local New York anchor Ken Rosato was axed from ABC 7 for allegedly referring to his co-anchor Shirleen Allicot with a four-letter word, sources exclusively tell Page Six.

The longtime local “Eyewitness News This Morning” anchor was “immediately fired” after “he called her a c–t” on a hot mic, a source said.

Rosato was off the air when he allegedly uttered the word, we were told, but insiders previously said his remark was picked up “on an open mic” and that he was “immediately let go.”

[Even if one cannot refrain from such name-calling in the workplace — and it should be relatively easy for adults to avoid — seasoned broadcasters are supposed to know the First Rule: The mic is *always* live. *Always.* The Second Rule of broadcasting is: See the First Rule. — Ed]
