Alec Baldwin on Thursday shot down a report from TMZ.com claiming he called one of its photographers a homophobic slur outside his Manhattan apartment hours after a woman was convicted of stalking him.

The gossip site published a video of Baldwin entering a car outside the apartment, during which he gets in a screaming match with two photographers and allegedly yells the slur.

"If @TMZ asserts that I used an anti-gay epithet, I will sue them," tweeted Baldwin, 55.

"Anti-gay slurs are wrong. They not only offend, but threaten hard-fought tolerance of LGBT rights," he said, adding that "acoustic analysis proves" the word he said was "fathead."

He did, however, cop to using an insult involving male genitalia.

Earlier in court, Genevieve Sabourin, 41, was convicted of stalking and harassment of Baldwin and his wife, Hilaria. Sabourin was sentenced to 210 days in jail.
