Marilyn Manson and lover Evan Rachel Wood had real sex in his latest music video, it has been claimed.The 38-year-old goth rocker and Wood, 19, reportedly refused to fake a lengthy sex sequence in Manson's new music promo for 'Heart-Shaped Glasses'.A source close to the production crew told Radar magazine: "They elected not to fake their intercourse. Though their genitals are concealed on-screen by bedclothes and each other's bodies, the video was originally intended to be shot in 3D, meaning their sex had to be shot from several different angles simultaneously. That meant the crew saw everything."And just to be sure they got it right, they got it on three times for the cameras."The Christian parents will be sharpening their steak knives for him."The rocker's representative has denied the sex scenes were real, saying: "It was simulated sex." In another scene, Wood - dresses as fictional teenage seductress Lolita - rubs her crotch while watching Manson perform on stage.

The video also features a shot of Wood lying drenched in blood.

Interscope record label are said to be releasing a toned down version of the video.
