Well, this is not great: Lindsay Lohan wrapped up a two-day filming stint for her upcoming Glee appearance yesterday, and sources are already complaining to the press about her behavior. Lohan was three hours late to rehearsal, if you trust E!'s anonymous source; the actress who plays Coach Beiste tweeted and deleted a similar complaint, though she did not name Lohan specifically. Meanwhile, Lohan's rep acknowledges that she was tardy but that it was due to a "misunderstanding" about her call time (and not partying, as some have obviously suggested). Still, it's only two days of work! Sleep on the set, do whatever you have to, Lindsay; just be on time. Update: Now Us Weekly says she was six hours late and had a list of "diva-like" demands. Oh boy.
