Winona Ryder Dishes Dirt on Mel Gibson

Dec. 17, 2010— -- While Winona Ryder's enjoying another moment in the sun thanks to her stunning turn in "Black Swan," she's also airing some dirty laundry, and not all of it is hers.

In the January 2011 issue of GQ magazine, Ryder claims she's known about Mel Gibson's not-so-palatable side for years. She shared an anecdote about the actor:

"I remember, like, fifteen years ago, I was at one of those big Hollywood parties. And he was really drunk. I was with my friend, who's gay. He made a really horrible gay joke. And somehow it came up that I was Jewish. He said something about 'oven dodgers,' but I didn't get it. I'd never heard that before. It was just this weird, weird moment. I was like, 'He's anti-Semitic and he's homophobic.' No one believed me!"

Gibson's publicist did not immediately respond to ABCNews.com's calls for comment.

Ryder's latest stint in the spotlight comes courtesy of her small but juicy role as an aging former ingénue displaced by Natalie Portman's budding ingénue in "Black Swan." After growing up on film sets, starring in some of the iconic roles of the 80s and 90s and seeing her career derailed by a shoplifting scandal, Ryder is no longer the new kid on the block.

"I did relate to Beth on a certain level," she said in the current issue of Elle about her character in "Swan." "Just that thing of, you know, when I'm told I'm not the ingénue anymore. And now I'm 39. I remember when I was younger, I couldn't wait to be older, because I was always the kid on the set, I was always younger than everyone else. And now I'm older than a lot of the people I work with. I've been doing this for 25 years, which is so strange."

"I was watching TV, and there was this oldies-but-goodies film fest, and 'Lucas' came on. I was like, 'Oh my God, I'm an oldie!'" Ryder recounted.
