Billie Eilish has responded to the trolls who said the 18-year-old singer has become "fat" after a picture showed her wearing a tank top. "Everyone's like, 'Damn, Billie got fat!'...And I'm like, 'Nope, this is just how I look! You've just never seen it before'," the singer told Vanity Fair. "It was a 110-degree (degrees Fahrenheit) day," the singer added.
