The actress was heading back to her Los Angeles home at around 2am (local time) when her car was struck by another vehicle.
A source tells UsMagazine.com, ""A couple of drunk girls hit her, got out of the car, giggled that she was famous, said something like 'Are you drunk, too?' Then they drove off.""
Michele noted down the girls' licence plate number and reported the accident to authorities.
The star's rep has since confirmed the incident, but insists the actress ""was not injured and is fine"".
