Billie Eilish has raised eyebrows among her followers after revealing what appeared to be bite marks on her body in a recent bikini photo.

The 22-year-old 'Bad Guy' songstress - who is currently gearing up for her world tour - took to Instagram to share snaps from her 4th of July celebrations, treating fans to a random selection of snaps, including a rare bikini selfie. The Grammy-winning artist - who is known for her love of oversized clothing - looked every bit the carefree star as she stuck out her tongue in a playful manner, posing in a pink halterneck bikini top, complemented by a towel wrapped around her waist and a firework in hand.

Billie's bikini snap quickly garnered attention, with one fan exclaiming: "The boobs are back," and another agreeing: "The second picture made me gasp".

However, it was the other images in the Instagram reel which sparked concern among more of Billie's fans. One image captured Billie sporting two conspicuous, fresh-looking bite marks on her arm. While another photo showed the marks having seemingly evolved into bruises as she posed in a mirror selfie alongside a friend.

Concerned comments flooded in, with one follower asking, "Wait are those bite marks? What's going on. This feels weird." Another added: "Is she...okay? Those bite marks look nasty."

Others wanted to know who had given Billie the bite marks, one commented: "Who the heck is biting Billie like that? And more importantly why is she promoting this. It's weird." Another added: "It's giving vampire. Not sure how to feel about this."

It is not the first time Billie has sparked concern on Instagram this year. In May, fans were left confused at why she was posting videos where she looked "unkempt" and "dirty".

Speculating over the snap in which the Oscar winner was covered in dirt, one person wrote on X: "Why [is] she looking like someone in [a] horror movie." Another then asked: "Why is she looking unkempt?" While a third offered: "She looks like she fell down in a puddle…" It was later revealed that Billie's bizarre look was part of a photo shoot that she did with Rolling Stone.

Billie is currently preparing for her upcoming Hit Me Hard and Soft tour, which will kick off on September 29 in Canada. The star is set to perform in the UK in July 2025.
