This week's art Instagram photos are diverse, yet there's an undeniable running theme of pop culture references. Although there are appearances by artists like Jeff Koons, JR, and Martha Cooper, there are also appearances by Slimer from Ghostbusters, The Simpsons, and our favorite mess, Amanda Bynes. Even Riff Raff randomly appears in a picture. It also covers major events in the arts, such as Les BALLETS de FAILE, the Venice Biennale, and even Red Bull Music Academy's work. This week's gallery is a ride, so buckle up and enjoy our compilation of The Best Artist Instagram Pictures of the Week.
