Actor Alec Baldwin has apologized for using an anti-gay slur. claims Baldwin called a photographer outside his apartment a “cocksucking fag” before getting into his car.

Baldwin denied the claim, saying he said “cocksucking fathead.”

GLAAD spokesman Rich Ferraro responded in a statement to “Mr. Baldwin can't lend his support for equality on paper, while degrading gay people in practice.”

Baldwin apologized in a series of tweets.

“Anti-gay slurs are wrong. They not only offend, but threaten hard fought tolerance of LGBT rights.”

“I'm grateful to all of the ppl I meet + hear from who recognize that I would never say something to offend my friends in the gay community.”

Five hours later, he added: “1-Rich Ferraro from @glaad informs me that c'sucker is an anti-gay epithet. In which case I apologize and will retire it from my vocabulary.”

If this sounds familiar, that's because Baldwin made headlines earlier this year when he called a tabloid reporter a “toxic little queen” in a tweet.
