The Bad Guy singer hit out at the reaction to the Variety magazine cover story in an Instagram post.
Singer Billie Eilish has accused a US entertainment magazine of outing her and questioned why it “matters”.
In a cover interview for Variety published on 13 November, the Bad Guy singer suggested she was attracted to women.
She told the outlet: “I’ve never really felt like I could relate to girls very well.
“I love them so much. I love them as people. I’m attracted to them as people. I’m attracted to them for real.”
In a Variety red carpet interview on Saturday, the star was asked about her sexuality, and added: “I didn’t realise people didn’t know.
“Why can’t we just exist? I’ve been doing this for a long time and I just didn’t talk about it.”
