Lady Gaga apologises for working with R Kelly

Singer-actor Lady Gaga has apologised for her past collaboration with R&B artiste R Kelly, who has been accused of sexual harassment by multiple women.

Gaga, who worked with Kelly on 2013's "Do What U Want (With My Body)", posted a lengthy statement on Twitter, saying she stands by the victims who have come forward with their stories of harassment.

"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," the singer said.

She said her collaboration with Kelly happened at a "dark time in my life."
