Former "Sesame Street" puppeteer Clash, who stepped down last year amid allegations that he'd had sex with underage males, now has a fourth lawsuit against him. And this time he's accused of holding a "crystal meth sex party" with the plaintiff. In the new suit, filed in U.S. District Court in Pennsylvania on Monday, Sheldon Stevens claims that he met Clash in 2004 at "a social networking event for models and actors." According to the suit, Clash later "lured: Stevens from Pennsylvania to New York "for sexual encounters," which the pair began engaging in when Stephens was 16. During one such encounter, the suit claims, a male chauffeur drove the pair to the chauffeur's apartment, where "they had a crystal meth sex party." "While in the apartment, Clash smoked crystal meth while engaging in sexual activity with Sheldon. Clash also gave Sheldon 'poppers' as a sexual aide," the lawsuit reads. "While Clash had sexual contact with Sheldon, the chauffeur watched and masturbated."
