Jonah Hill

Jonah Hill has apologized for using a homophobic slur, calling it "disgusting."

Over the weekend, TMZ posted a video of the Oscar-nominated actor lashing out at a paparazzo, saying, "Suck my d---, you f----." Following the confrontation, Hill went on Howard Stern's radio show Tuesday to apologize.

"This is a heartbreaking situation for me," Hill said. "I'm upset because from the day I was born, and publicly, I've been a gay rights activist. ... I said a disgusting word that does not at all reflect how I feel about any group of people."

Hill goes on to talk about what exactly lead to him using the word. "Just to give it some context, not excusing what I said in any way, this person had been following me around all day, had been saying hurtful things about my family, hurtful things about me, and I played into exactly what he wanted: I lost my cool. I'm not at all defending my words, but I'm happy to be the poster boy for thinking about what you say. ... I shouldn't have said that."
