Jonah Hill apologizes for gay slur to paparazzo

NEW YORK -- Jonah Hill has apologized for using a gay slur with a paparazzo in an encounter caught on video.

A video posted Tuesday by TMZ shows a photographer pestering Hill, who eventually responded with muttered expletives and an anti-gay expression. On "The Howard Stern Show" on Tuesday, the 30-year-old actor acknowledged that he said "a disgusting word."

Hill said the word "does not at all reflect how I feel about any group of people." He said that he's been a gay-rights activist "from the day I was born."

Earlier this year, Hill promoted a Human Rights Campaign effort opposing anti-gay laws in Russia ahead of the Winter Olympics.

Hill said he had been harassed by the photographer, claiming he said "hurtful things" about Hill and his family.
