Lindsay Lohan’s friends reportedly enabled the underage starlet to drink at restaurants before her admission to rehab last week.

Lindsay had previously denied drinking in public but an onlooker at Orso in Los Angeles last week spotted her drinking cocktails over lunch.

The source told TMZ that Lindsay rolled up to the restaurant and ordered a cocktail to go with her salad but was refused when she couldn’t show any ID. She then asked for a glass of water instead but her older friends ordered drink after drink, which Lindsay drank.

The onlooker added that after the mostly liquid lunch, Lindsay drove away from the restaurant in her convertible.

In related news, Lindsay’s spokesperson Leslie Sloane Zelnick has confirmed that Lindsay will keep working on her new film I Know Who Killed Me while in rehab at the Wonderland Center: “She will continue working but will spend her nights at the recovery facility.”
