Fans Angry Katy Perry Janet Jackson Cover

Earlier this week, Katy Perry kicked off her Witness world tour, but unfortunately she is already facing some major backlash.

While in Montreal, Katy did a cover of Janet Jackson‘s iconic hit song, “What Have You Done For Me Lately”, even copying Janet’s choreography at the 1987 Grammy Awards, as The Fader reports.

Although a lot of Katy fans defended her actions (since many artists perform covers), Janet stans weren’t having it.

Gentrification is not the right term, my dear. "Executed Not As Well As Hoped" would suffice. She tried. She didn't. That's it.
