Lindsay Lohan and Sam Ronson drama re-ignited this weekend.

At L.A. club Trousdale Friday night, Lohan, 23, threw a drink at her DJ-ex, 32.

Asked why Lohan tossed the drink at her, Ronson shrugged her shoulders and told a TMZ cameraman, "I don't know ... she's an angry human being."

Lohan had a rough week.

On Thursday, her estranged father Michael attempted to stage an intervention and barged into her home with officers from the Los Angeles County Sheriff's Department (who determined the actress wasn't under any danger).

Then, reports surfaced that Lohan was axed from the upcoming indie fantasy comedy The Other Side.
