Katy Perry is facing backlash for again working with music producer Dr. Luke… almost 7 years after being dragged into his legal battle with Kesha — who seems to have chimed in.

According to Rolling Stone, Katy is collaborating with a slew of music producers for her untitled 6th studio album. Per the report, Katy has tapped the producers who helped make hits on her albums “Teenage Dream” and “Prism” … including Max Martin, Dr. Luke, Stargate, among many others.

Because Katy is going back to Dr. Luke well for her new tunes — Kesha’s fans are PISSED and dragging her for the decision … calling it a betrayal. And Kesha seems to agree.

Like we said … Kesha herself also appears to have acknowledged the news — taking to X and simply writing “lol” without any context … this on the heels of speculation KP had recruited Luke.

Remember, Kesha accused Dr. Luke of sexual assault in a 2014 lawsuit — but Dr. Luke denied the allegations, hitting back with a lawsuit of his own — suing Kesha for defamation.

Kesha chose to drop her lawsuit in August 2016 … but Luke’s defamation suit wasn’t settled until June 2023. She noted in a statement at the time … “Only God knows what happened that night … I am looking forward to closing the door on this chapter of my life and beginning a new one. I wish nothing but peace to all parties involved.”

It’s unclear if Luke helped produce Katy’s forthcoming single ‘Woman’s World’ … or if he touched other tracks on the album. Either way … it’s certainly a choice, for better or worse.

Katy hasn’t addressed all the backlash. We’ve reached out to Kesha … no word back yet.
