The embattled actress was reportedly turned away from Madonna and Demi Moore's Oscar party - despite Josh Brolin vouching for her.
Lohan was not allowed in to the party thrown at the Beverly Hills home of talent agent Gus Oseary after turning up with her brother and security team, the New York Daily News reports.
The actress felt she would get in as Oseary works for Untitled Entertainment, which represents her as well as Madonna and Moore.
When Brolin showed up and saw Lohan struggling to get past party organisers he asked them, 'Don't you know who this is?'
The doormen replied they did but that Lindsay was still not getting in, leaving Lohan reportedly muttering, 'This is so humiliating.'
Representatives for Lohan, Moore, Madonna and Brolin did not respond.
