The 27-year-old actress has been accused of acting immaturely and causing drama by her new friends, who are all around 10 years younger than her, reported New York Post.
The claims come after the troubled starlet, who checked out of rehab this summer, reportedly showed up at a party to visit her former flame, 18-year-old male model Morgan O'Connor, and supposedly told all other girls to leave before locking herself in a bathroom.
"She finds out where Morgan is, then shows up and causes problems. Morgan was staying at the Dream Downtown, and Lindsay showed up and found out which room he was in. She knocked on his door, came in and started bitching Morgan out," a source said.
The rich teens called hotel security to try and help calm 'chronically distraught' Lohan, who reportedly went into a meltdown when Morgan refused to kiss her.
