AnnaLynne McCord, who once acted out a rape scene on her hit show "90210," recently revealed that she had once been sexually assaulted.

McCord opened up about the incident at the Life is Love event in Los Angeles on Sept. 22. The event benefited the Somaly Mam Foundation which works to end modern day human trafficking and empower victims.

"Has anyone ever been raped? Sexually abused? Not said 'no' when you felt you didn't have the right to?" the "90210? star said during a speech at the event. "I know what it feels like."

McCord, 25, told Us Weekly after the event that she had been in a "similar experience to what these girls go through 20 times a night."

"It happened to me once by somebody that I knew, and it is a very interesting thing to feel that you do not have the voice to say 'no,'" McCord told the mag. "It wasn't an attack or anything like that. I just had no voice. I did not know how to say, 'I don't want this. Please do not do this to me.'"

The CW star went further, explaining that the altercation happened while she was in her own home, adding that her "hospitality was taken advantage of at an extreme level."

This is the first time the actress has opened up about her sexual assault past. On "90210's" second season finale, McCord's character, Naomi Clark, was raped by her high school teacher.

"I did not have a voice, and now I do, and I'm practicing using my voice for others. Finally I can say I was taken advantage of - not from my own shame that I did something to deserve that - and now I can have a clear conscience."

McCord's co-stars Shenae Grimes, Jessica Stroup, Matt Lanter, Justin Deeley and Ryan Eggold were all in attendance when McCord revealed she had been sexually assaulted.
