In addition to showing up late or not at all for work, Robinson's letter accused Lohan of acting "like a spoiled child and in doing so ... [alienated] many of [her] coworkers and endangered the quality of this picture." Plus, the tough old dude (Robinson is 70, and clearly has no time for some spoiled kid's BS) is not buying any of her "Oh, I don't feel well" crap: "We are well aware that your ongoing all night heavy partying is the real reason for your so called 'exhaustion'. We refuse to accept bogus excuses for your behavior." Daaaaang!
By Monday, this is either going to spun like crazy by Lohan's flacks (who should be earning at least six figures for the gig), or she'll be off the movie.
