What Was I Made For hitmaker Billie Eilish didn’t hold back in a slew of snaps posted early in January, showing her working on new music and bending over underneath a tree.

Billie Eilish had fans in meltdown as she bent over to show off her peachy rear underneath a huge Christmas tree.

The Bad Guy songstress shared a January photo dump with her followers on Instagram, which included one iconic snap of Billie’s top half disappearing under a huge tree decorated with lights, baubles and ornaments. She wore a pair of dark blue baggy jeans and an oversized hoodie while propped up on two small steps, bum in the air.

A pair of simple white socks covered Billie’s feet in the cheeky picture as she celebrated the festive season with her family. In another close-up snap, she sat in the back seat of a car with one hand in her neon red hair, blinking lazily into the camera lens in an emerald green cardigan.

With a gold pendant necklace around her throat and pearl earrings dotting her lobes, Billie applied spidery mascara to her lashes and a hint of blush over her freckles, before adding a pink pout and arranging her full fringe into curtains.

Fans got emotional over the first picture she shared, which showed Billie crooning into a microphone in the recording studio – hopefully working on some new music.

Along with doing a jigsaw puzzle with her family and dancing around in what looked like a hotel lobby, she asked fans: “How do I not buy every car?”

Billie finished off the post with the simple caption: “Another January [yawn emoji].” Fans soon rushed to the comments section to heap praise on her, with one writing: “Okay lover where’s the album?”

“You’re so perfect miss ma’am,” another gushed. While another echoed: “Girl where is the album?!” and somebody else penned: “If you’re reading this I love you.”

Over the Christmas period, Billie celebrated her birthday with a very NSFW sex toy – resting a purple dildo on her head as she posed for a photo. Someone else’s hands could be seen holding the toy up to her head while Billie grinned knowingly into the camera.

She later played a raunchy game of Twister with pals, leaning over one of her friends to stick her bum right in the air in a pair of tight trousers and black lace tights. Though she tends to opt for baggy clothes to avoid “being sexualised”, she has previously admitted that she’s a “sexual being”.
