Lindsay Lohan's friends say she knows she has a problem

Lindsay Lohan’s friends said the troubled actress finally accepts that she has a problem after failing two drugs tests, including one for cocaine, TMZ reported Sunday.

Friends said she’s “beating herself up over this,” and that she “feels like she just ruined all these really great opportunities that were coming her way,” TMZ said.

Lohan, 24, spent Friday and Saturday nights in AA meetings, reports said.

She faces up to 30 days in jail for each failed test.

Lohan’s reps didn’t return calls for comment.
