She entered on a white version of the BTW Ball horse (literally look they are the same) and did the the second performance of the BTWB which is government hooker and replaced the song with Do What You Want. It's basically the BTWB at the AMAS.
xD when i saw this i screamed "Government Hooker!!!" and wrote that on facebook lol and a friend thought "what? is she performing Gov Hooker? what's happening?" cause the poor thing could not watch it xD (she saw it later) Gaga was singing Do What You Want but the desk part was so Gov Hooker at BTW Ball! <3 xD
