AceShowbiz - Billie Eilish got emotional as she opened up about her body image in a candid spread for British Vogue. In the upcoming May issue, the 23-year-old singer got candid about her personal struggles, her decision to go vegan, and how her artistry has shaped her as a person.

Billie was left in tears when Nicki Minaj touched upon her feelings about beauty. Minaj asked, "This may be an odd question, but you seem to be a bit uncomfortable with how beautiful you are at times. I could be wrong."

Billie, visibly moved, admitted, "I've never really felt very beautiful or seen myself in that way." She added, "I've had to really convince myself that I am beautiful. Being a woman is hard."

Billie further revealed that her switch to veganism was initially driven by her body image struggles.

When asked by Stella McCartney about her vegan journey, she confessed, "I went vegan mainly because I hated my body and I thought I would lose weight. But then I learnt all about the dairy industry and the completely horrific and disturbing animal agriculture that we all just pretend is normal and OK."

Reflecting on how her confidence and self-perception have evolved, Billie shared with Michaela Coel, "I had no idea [when I was younger] that I was doing anything fearlessly."

"When I would hear people comment that I was only 16 and not fitting in with the stereotype - that I was a rebel or whatever - I remember being really confused because I didn't see it that way," she continued. "I just felt like I was doing what I thought was cool. I was not intentionally trying to break any mould or rules or change music."

As Billie grows older, she acknowledges the increased pressure and scrutiny from the public. "It was hard to remember to trust myself or even believe in myself sometimes. It's still a process. I think I'm doing pretty good. I've also always been very strong-willed and very much myself, so I do think that plays a part," she reflected.

Pondering her future, Billie shared with Greta Gerwig her hope for a long, fulfilling life. "God, if I even live to 85, but if I do I would love to be embracing who I am, embracing being old, hoping the world hasn't ended yet," she mused.
