Jennifer Lopez’s has been slammed for working with Dr. Luke

Jennifer Lopez has been slammed for working with Lukasz Gottwald, known as Dr. Luke, on her new single.

Ain't Your Mama was written by Megan Trainer, and produced by the controversial music producer– who is at the centre of a court battle between Sony Music and singer Kesha, who accused of sexually and physically abusing the Tik Tok singer.

People have taken to Twitter to brand J.Lo, 46, "insensitive" and a "hypocrite”.

But according to Meghan Trainor, 22, Lopez had nothing to do with Luke's involvement, and a source told E! news that Trainor wrote "Ain't Your Mama" and worked with Dr. Luke years ago—before Kesha filed her lawsuit.

"I felt terrible when Jennifer got all the hate. I texted her the song and she had no idea," Megan told Digital Spy. "She thought I did it alone by myself at my house, which a lot of people think because I do do that.

"I sent it to her and said, 'Do you like the song?', and she said, 'I love the song, my kid loves the song — he's made me play it five times already, so I know it's a hit — when can I cut it?'. So I said immediately, 'Whenever you want!'"

Trainer and Lopez are both signed to Sony, who work with Luke's Kemosabe Records.
