Billie Eilish Winks Showing Cash Bills Tucked Into Her Underwear

Billie Eilish isn't one to flash her undies often, but her February outfit was revealing enough to showcase both her feathery black bra and the bills of cash she'd tucked into it. Making headlines earlier this year for stripping down to a low-cut waistcoat as she attended the 2024 Grammys After-Party, the 22-year-old singer flaunted her curves in a rare moment, and fans didn't take long to break down her look. Fans following the @eilishoutfits feed on Instagram even got an itemized breakdown of the singer's ensemble as she chose luxury lingerie brand Agent Provocateur.

Scroll for the photo. Partying with friends and clearly having a good time, Billie winked for a fun snap as she highlighted her figure in her all-black look. The songwriter had gone busty in the Agent Provocateur Julietta Waistcoat, one retailing for over $800.

Billie, who had donned Agent Provocateur lingerie for her headline-making 2020 Vogue cover, opted for a plunging, figure-hugging waistcoat in black, one boasting fine silk fabrics, button accents, plus a built-in feather bra that accentuated her cleavage.

With some cash tucked into one side of her top, Billie Eilish was clearly letting her hair down during the high-profile night. Wearing chunky silver earrings to match her necklace and showing off red-tinted hair worn down, the "Ocean Eyes" hitmaker drove fans wild with her curves, although those seeing the waistcoat's price tag did seem a little disappointed.

"Every time Billie wears something I could actually see myself in it’s always super expensive in USD," one fan replied. "Am i the only one noticing she keeps dollars in her bustier," another wrote, spotting the cash.

Billie had made headlines for another busty red carpet look late last year, rocking up in a pinstripe, shirtless suit for the 3rd Annual Academy Museum Gala in Los Angeles, held last December. Going eye-popping in what was likely a push-up bra beneath her revealing jacket, the American-born pop sensation had her outfit all over the internet within minutes of being photographed, and this one didn't come cheap, either.

Billie Eilish, who has a $53 million net worth, had chosen Kardashian-adored designer Jean Paul Gaultier for her look.

Billie recently opened up to reveal that despite being an A-list celebrity, she still gets ghosted.

"I was like, did you die? Did you literally die?," she told British singer Lily Allen earlier this month, adding: "It was somebody that I’d also known for years and had a plan, the day of, on the phone, making a plan, this is my address, be there at 3pm - never heard from him again. Ever. I couldn’t believe it."
