Lady Gaga, Raped At 19, Experienced 'Paralyzing Fear' for 10 Years

New York: Lady Gaga on Friday described her Oscar performance with rape survivors as the most difficult of her life, saying that she remains in chronic pain from a decade-old assault.

The pop star offered an emotional performance of her song Till It Happens To You at the 88th Academy Awards on February 28, with university students, who are rape survivors joining her on stage with arms joined in solidarity.

"I was never such a wreck as I was the week before this performance," the 29-year-old singer told New York radio station Z100.

She also said: "It's the thing that I am the most ashamed of in my life and I have always felt that it was my fault until this week."

Gaga, who turns 30 this month, has previously revealed that she was raped by an older man when she was 19.

But she said that the Academy Awards performance marked a coming out of sorts, as previously the issue was "swept under" with people quickly moving on to other topics.

"People don't know this about me because I don't share it, and I know they see me as this kind of celebrity that has success and money and the world watching and that I must have no problems. But I actually suffer from chronic pain all the time and it's from this paralyzing fear that I've experienced for almost 10 years," she said.

Gaga, whose real name is Stefani Germanotta, said that she had compartmentalized the experience in the back of her mind but that it "stays in your body, in your tissues."

"So I feel physical pain, and there are a lot of people who suffer from chronic pain who have been through a traumatic experience," she said.

Gaga said that she later got matching tattoos with some of the young people at the performance, who had come on stage with slogans written on their arms such as "Not At All Your Fault" and "Unbreakable." (Also Read: Oscars: Lady Gaga Delivers Powerful Tribute to Rape Survivors)

Gaga was nominated at the Oscars for her song which appears in The Hunting Ground, a documentary about rape on university campuses.

She was introduced by Vice President Joe Biden who encouraged viewers to sign a pledge on the site itsonus.org.

The pledge, which has seen a surge of interest since the Oscars, commits the signatory to intervene in situations when a person has not or cannot consent to sex.
