Only a few weeks after Lindsay Lohan was ordered to wear an alcohol-monitoring device, she’s found herself in trouble yet again. Lohan was forced to post $200,000 bail Tuesday evening to avoid being detained, after a judge issued a warrant for her arrest. Sources said the device’s alarm went off Sunday evening, the night Lohan was attending the MTV Movie Awards; her attorney said the device detected a small amount of alcohol that night, but that she could not “verify its accuracy.” LiLo, who did not appear in court, spent the night frantically tweeting, of course: “My scram wasn't set off-Its physically impossible considering I've nothing for it to go off-All of these false resports are absolutely wrong,” she posted at about 5 p.m. Her mind quickly moved on to other topics, though, tweeting a few hours later: “cinderella man off of eminem's new record is insane!” and “TRUE BLOOD COUNTDOWN! starting now.... hehe."
