Billie Eilish has discussed how she feels about her body and revealed that looking at images on social media can make her feel "really bad" about herself.

In an interview with The Guardian to promote her second album Happier Than Ever, the 19-year-old singer-songwriter spoke about her insecurities which are exacerbated by social media comparison, even though she knows many of the images have been retouched.

"I see people online, looking like I’ve never looked," she said. "And immediately I am like, 'oh my God, how do they look like that?' I know the ins and outs of this industry, and what people actually use in photos, and I actually know what looks real can be fake.

"Yet I still see it and go, oh God, that makes me feel really bad. And I mean, I’m very confident in who I am, and I’m very happy with my life... I’m obviously not happy with my body, but who is?"

The singer explained that her new song OverHeated is about people who "promote unattainable body standards".

"It's completely fine to get work done – do this, do that, do what makes you feel happy," she said. "It's just when you deny it and say, 'Oh, I got this all on my own, and if you just tried harder, you could get it.’ That makes me literally furious. It is so bad for young women – and boys, too – to see that."

The singer said she has to "disassociate" to feel comfortable on stage.

She shared: "When I’m on stage, I have to disassociate from the ideas I have of my body. Especially because I wear clothes that are bigger and easier to move in without showing everything – they can be really unflattering.

"In pictures, they look like I don’t even know what. I just completely separate the two. Because I have such a terrible relationship with my body, like you would not believe, so I just have to disassociate..."

"Then you get a paparazzi picture taken when you were running to the door and had just put anything on, and didn’t know the picture’s being taken, and you just look how you look, and everyone’s like, 'Fat!’"

She agreed that it's "weird" to have her body dissected in this way.

"Yes! I mean, we only need bodies to eat and walk around and poop. We only need them to survive. It's ridiculous that anybody even cares about bodies at all. Like, why? Why do we care? You know, when you really think about it?" Eilish added.
