"I stand behind these women 1000%, believe them, know they are suffering and in pain, and feel strongly that their voices should be heard and taken seriously," Gaga tweeted of the women's claims, which Kelly has denied.

The "A Star Is Born" actress promised to pull her 2013 song "Do What U Want (With My Body)," a duet with Kelly, from streaming services and Apple's iTunes store. She added that she "will not be working with him again."
