Lindsay Lohan, trying hard to stay sober and out of trouble, found herself at the center of a new kerfuffle on Wednesday after an aborted trip to a Hollywood night club. The “Mean Girls” actress was accused by a nightclub manager of grazing his knee with her car while trying to avoid paparazzi and drive away in her Porsche from a friend's birthday party. But Lohan said the claims were “absurd” and a “complete lie”, while police said there was no evidence anyone had been injured. “Scrape? This is all a complete lie,” Lohan said on her Twitter account, after completing her latest stint of court-ordered community service at the Los Angeles morgue on Wednesday.
