Socialite Nicole Richie is bracing herself for a video prank so foul that Jackass star STEVE-O fears he'll have to cover her face when it airs on his new film - to hide her identity. The prankster refuses to go into detail about what the Richie segment of his new video PAPARAZZI STUNTMAN contains, but he knows The Simple Life star, who was romantically linked to him earlier this year (06), will be far from happy. He says, "(The film) is all celebrities I don't have releases from, (like) Nicole Richie - but I'm just going to cover up her face and say, 'Someone really famous.'" And Richie isn't going to be too pleased by remarks Steve-O made in US magazine FHM about their rumoured romance. He laughs, "I never humped her. I jerked off in her bed."
