Janice Dickinson -- Beverly Johnson Tells the Truth About Cosby

Janice Dickinson was filled with contained emotion as she told our photog ... Beverly Johnson is an icon and a stand-up woman who told the truth about Bill Cosby.

Dickinson was out and about in Bev Hills Thursday when we asked her about Johnson, who says Cosby drugged her during an audition at his home for Cosby's wildly popular TV show.

You literally feel the emotion as she speaks. Janice is not so sure about "South Park" mocking Cosby this week. She's not protesting, but she doesn't see the funny in alleged sexual assault.
