According to People, Lindsay Lohan’s lawyer confirmed that the actress tested negative for alcohol after her SCRAM bracelet was set off at an MTV Movie Awards after-party. People reports, however, that the L.A. district attorney spokeswoman did not know about the test results, and, ultimately, it’s still not clear why the bracelet had set off an alert. Lohan’s probation violation hearing will take place on July 6.
