Amanda Seyfried has revealed that she first watched pornography when she was just six

Hollywood A-lister Amanda Seyfried has revealed that she first watched pornography when she was just six years old.

In a candid interview with GQ magazine the Lovelace actress said that the X-rated video unsettled her and had profound impact on her views on sex.

"It was a cop - a guy dressed in a cop costume, and it was a girl going down on him," she said. "It was the first time I'd ever seen a penis, and I remember it being very graphic.

"I remember when he came - it was so terrifying. It was funny. But it was also, like, so, so, so wrong."

Seyfried went on to say that as result of watching the video she feared sex.

She said: "It was 1990 or 1991 and so Aids was really rampant. Watching any kind of sexual acts when you're a six-year-old would make you think you were going to contract Aids somehow."

The 27-year-old, who stars as Linda Lovelace in the biopic about the star of crossover porn film Deep Throat, also voiced her concerns about children being exposed to pornography - especially the effect it could have on how boys treat women when they are older.

"I think it's probably a bad idea for young boys to see how [women are] being depicted in men's fantasies," she said. "It could get very dark. You could learn how to do things wrong."

Lovelace is scheduled to hit UK cinemas on 23 August.
