Lindsay Lohan has been branded "childish" by her so-called friends.
The 27-year-old actress has been accused of acting immaturely and causing drama by her new pals, who are all around 10 years younger than her.
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.
A source told the New York Post's Page Six column: "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.
"She was ordering all the girls to leave, telling one that her Balmain jeans were fake. She said she wouldn't leave until they all left. These kids are 18."
The rich teens called hotel security to try and help calm "chronically distraught" Lindsay, who reportedly went into a meltdown when Morgan refused to kiss her.
The eye witness added: "They honestly didn't know what to do. They assumed it was Lohan's room. She called her dad and locked herself in a bedroom and wouldn't come out. It's childish stuff. She's chronically distraught.
"Every time she comes around, she causes problems. Morgan's modeling, he's going to the gym, working for charities - he's got stuff to do. He doesn't want to be around Lindsay or her behavior."
