Last night Lindsay Lohan was supposed to fly to Austria to accompany Richard Lugnar to the Vienna Opera Ball this evening, but the starlet missed her 7pm flight! Lindsay even tried to grab a seat on another jet, but the plane was completely full so she gave up and went home, partying until the wee hours of the morning with her sister Ali.

Lindsay, her assistant and Ali started off at the Chateau Marmont around midnight, and then they went to the Tea Room around 1:45am, but she only stayed for about 15 minutes, chatting with the owner and sitting at their table. A source inside the club tells X17online exclusively:

    "Lindsay looked super stressed and antsy when she arrived at her favorite Wednesday night haunt. She showed up in a rush, hung out for about 10 minutes and then left with the owner around 2am. Her facial expressions were even apparent in the pitch dark club - she didn't look drunk, but she definitely looked like she was freaking out about something."


After the Tea Room, Lindsay headed to a private house party, where sources tell us she stayed past 4am! And mind you, this was with her little sister Ali, who is just 16! Maybe she needed Ali to console her after missing her flight?
