Kesha, aka GASHa, ruined Katy's career by LYING about Dr. Luke attacking her. Katy was fearful of the backlash and stopped working with him. Bye hits.

GASHa is also a flop now and future star of Where Are They Now? segments and #3 on the line-up of Oldies acts at an amusement park near you.

Katy, at least, can bring her nine #1 hits to small theaters and large clubs for the next 20 years.
