Lindsay took her 15 year-old sister Ali to Nylon's Young Hollywood party at the Roosevelt Hotel in Los Angeles on Monday but refused to let photographers at the event take photos of her and her sis sitting together.
Aside from the fact that Ali really shouldn't be out partying at a Hollywood event, Lindsay was reportedly drinking and didn't want to be photographed.
"Lindsay was definitely in party mode, but didn't want anyone seeing her drink," a spy tells Page Six.
Before she whisked her sister away to Hawaii for a little family vacation, Lindsay was also spotted partying with Ali at Hollywood hotspot MyHouse. Only problem is the nightclub is strictly 21 and older.
"The club promoter asked Ali to leave twice before she was finally escorted out," a partygoer tells Hollyscoop.
Lindsay isn't exactly being the best role model for Ali, but than again, the alternative is Dina Lohan, who really isn't any better.
