Jackass star STEVE-O is launching a new career - as a rapper. The prankster, whose stunts have included stapling his testicles to his leg and having a lifesized tattoo of his own face etched on his back, claims he has been in discussions with Universal Records and is planning an album. The star - real name STEPHEN GLOVER - made the announcement at a performance by METAL SKOOL in Hollywood, after he was called onstage by singer MICHAEL STARR. Steve-O then gave the audience a sample of his rapping before dropping his trousers to flash his backside at the cheering crowd.
