Comedy star Seth Rogen was reportedly thrown out of a party for his own movie, Pineapple Express, after fellow revellers accused him of smoking marijuana.Rogen was attending a recent aftershow for his latest movie, when members of the crowd began suspecting the funnyman was smoking a cigarette rolled with more than just tobacco.A source tells the New York Post, "He was told to put it out immediately or leave."In an article published in Elle magazine this month Rogen mused to reporters of his "terrible case of I-wanna-smoke-weed-all-day".A spokesperson for the Superbad star has declined to comment on the incident.
