Vanessa Williams is bravely speaking out about being molested at the age of 10.

The blue-eyed actress, who first told of her abuse in her 2012 memoir 'You Have No Idea,' opened up about the harrowing ordeal in a new episode of 'Oprah's Master Class,' where she spoke of the incident with candor, honesty and courage.

Williams revealed that the abuse occurred by an 18-year-old friend of her family's when she was visiting them out in California.

"One night, she came into the room where my friend and I were sleeping, and she told me to lie down on the floor. And she took my bottoms off, and she said, 'Be quiet,' and she went down on me," Williams revealed. "And at 10 years old, I had no idea what it was, but I knew it felt good. And I knew I shouldn't be saying anything. And I didn't tell anyone. And I knew it felt good -- but also something that wasn't supposed to be happening."

Though she wanted to talk to her parents about it, when she returned to New York she had just found out that her uncle had died, and suppressed the abuse -- though it made a significant impact on her life.

"At that young age, having that happen to you in your body, it awakens your sexuality at an age where it shouldn't be awakened," she shared. "I think that had that not happened in my life … there wouldn't have been that shame that was kind of always haunting me. I think that it made me more sexually promiscuous and more curious at an age younger than I should have been."
