Amanda Bynes Mug Shot — Short Hair and a Scowl

Amanda Bynes had to remove her platinum blonde wig when she posed for her mug shot last night … revealing a super short hair cut … and Bynes didn”t appear happy about it.

Bynes sported a scowl and a black shirt when she posed for the photo … following a bong-throwing arrest in NYC last night.

The 27-year-old actress arrived to court this morning to face a judge — wearing the wig again — but it was clear she didn”t want to be photographed.
