Amanda Bynes isn't letting last week's DUI arrest stop her from getting her party on!
The former child star left Greystone Manor after a night of hanging with friends wearing short black jean shorts and a black razor back tank dress ...exposing her lacy bra. Um, ok.
Bynes, 26, was arrested last Friday at 3am for driving under the influence after her BMW clipped a police cruiser at the intersection of Robertson and Santa Monica Boulevard.
After checking out these photos and the below video ... she's sexy and SHE knows it!
