After facing backlash for her silence, Lady Gaga apologized late Wednesday for her 2013 duet with R. Kelly and spoke out in support of all the women who have accused the rapper of sexual assault.

The singer, 32, collaborated with R. Kelly on the track “Do What U Want (With My Body),” a song that was made during “a dark time” in her life, she said in a statement posted on Twitter. She vowed to remove the song from iTunes and other streaming services to support the women who have spoken out against Kelly in the Lifetime docuseries “Surviving R. Kelly.”

"I stand behind these women 1000 percent, believe them, know they are suffering and in pain, and feel strongly that their voices should be heard and taken seriously," Gaga said. "What I am hearing about the allegations against R. Kelly is absolutely horrifying and indefensible."

"As a victim of sexual assault myself, I made both the songs and 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," she said.

'SURVIVING R. KELLY' PRODUCER SLAMS LADY GAGA FOR SILENCE ON SEXUAL ABUSE ALLEGATIONS

Gaga was called out earlier this week by a producer of the docuseries for refusing to speak on the show about Kelly’s history of sexual and domestic abuse allegations. She was also slammed for her 2013 live performance with the singer and for praising him a year later on Twitter.

The “A Star is Born” actress acknowledged her younger self’s “poor judgment” and ended her statement with an apology.

“I’m sorry, both for my poor judgment when I was young, and for not speaking out sooner,” she said. “I love you.”

Shortly after Gaga's apology, video surfaced on social media of what appeared to be Kelly partying at a nightclub in Chicago as his songs played in the background.

Meanwhile, Kelly has steadfastly denied all allegations of sexual misconduct and abuse and reportedly vowed to sue everyone involved with the production and airing of the Lifetime docuseries.

State attorneys in Cook County, Ill., this week urged Kelly's accusers to come forward with their allegations against Kelly.
