Lindsay Lohan is calling BS on a hookah lounge manager, who claims the actress injured his knee when she allegedly grazed him with her Porsche last night -- insisting, "This is all a complete lie."
Lindsay took to her Twitter account moments ago to blast the allegation -- writing, "Scrape? This is all a complete lie. I've been at community service. Last night, I attempted to wish a friend happy birthday, which I didn't even get to do because I was freaked out by all of the paparazzi."
Lindsay adds, "These false accusations are absurd."
