The 'American Idol' judge took heat on Twitter as fans showed their support for Kesha.
Jennifer Lopez ain't your mama and people ain't happy with the diva about it.
The 46-year-old singer released her new single, "Ain't Your Mama," this week and fans quickly noted that the track was co-produced by Dr. Luke -- the same producer that Kesha accused of drugging and sexually assaulting her. (Dr. Luke has called Kesha's claims "outright lies.")
Lopez performed the song -- which was co-written by Meghan Trainor -- during the American Idol finale on Thursday. Sources tell ET that "Ain't Your Mama" was actually written years ago, with Dr. Luke producing at the time -- well before Kesha's lawsuit was filed.
Lopez, who returned to Sony's Epic Records earlier this year, recorded the song within the last two months after falling in love with the track and never worked with Dr. Luke -- who wasn't involved in the final product -- on the song.
Meanwhile, fans have been @replying the pop star to express disappointment in who she has chosen to work with.

"I'm disgusted to see that this was produced by Dr. Luke. I can't believe you, I'm disappointed in you, and I won't listen," one Twitter user wrote to J.Lo, a sentiment that was echoed by many more.
