Billie Eilish sent fans a big smile as she stripped down to a plunging bikini top back in 2023. Posting on Instagram three years ago, the singer showed off her oceanfront curves by a rocky shore, squinting in the sunlight while going 100% makeup-free. Displaying her sensational cleavage in a low-cut swimsuit, Billie afforded a rare view of her curves, pulling a total 180 on the usual baggy wardrobe she wears to conceal them. The 24-year-old, who snapped her selfie while wet-haired, had fans gushing over a recent repost of the shot on X, and it was here that a fan actually asked the platform's AI tool Grok to put more clothes on her.

Wearing her hair down, wet, and a little slicked back, Billie ditched the colorful hair dyes, going for a near-black look as she showed off her clear skin. The "bad guy" hitmaker added a pendant necklace and discreet earrings to complete her look, one she posted on Instagram in June 2023 while enjoying a vacation with friends. The photo was reposted on X just this weekend.
"Beautiful girl," one fan replied. "Nice view," another said. While users on X often ask Grok to undress a celebrity or put her in a bikini, the fan replying to this post went for the opposite. Joking that Billie Eilish was actually showing too much skin, they told Grok to "Make her ware legal." Grok is currently in hot water over its deepfakes scandal.

2023 also brought this busty shot as Billie Eilish flaunted her curves in a MIAOU swimsuit while chilling in her backyard. Topping up her tan while modeling a multicolored, patchwork-style bikini, the Gucci promo face flashed her cleavage and her new chest tattoo, quickly attracting a fan response.
"Talented and beautiful, nothing else need be said," one Daily Mail user wrote as the media outlet covered her social media share. Noting that Billie is renowned for not showing her figure, another gained likes for saying: "She’s beginning to do exactly what she said she wasn’t gonna do."
