(CNN) Lady Gaga has apologized for working with R. Kelly and said she plans to remove their 2013 single from streaming services.

A recent Lifetime documentary chronicles allegations of abuse, predatory behavior and pedophilia against Kelly, and Gaga has been under fire to condemn him. Kelly has strongly denied the allegations.

Gaga's single "Do What U Want (With My Body)" featured vocals by Kelly, which was controversial at the time because the R&B singer had stood trial in Chicago on child pornography charges a few years prior to the single's release. Kelly was acquitted.

"As a victim of sexual assault myself, I made both the song and the video at a dark time in my life, my intention was to create something extremely defiant and provocative because I was angry and still hadn't processed the trauma that had occurred in my own life," Lady Gaga said in a statement.
