Katy Perry and Rebecca Black's Friday Night was Epic!
Last Friday Night. Do it all again!
We are loving Rebecca Black's appearance in Katy Perry's music video for Last Friday Night! Work it girl!
Not to mention appearances by our favorite Glee boys: Kevin McHale, who plays Artie, and Darren Criss, aka Blaine.
Watch the video and tell us what you think!
