Billie Eilish has shared a behind-the-scenes look at her acting debut and posted pictures of herself covered in blood on social media.
The 21-year-old singer is guest-starring in Donald Glover's new thriller series Swarm, in which she plays a cult leader called Eva.
Billie took to Instagram on Sunday to share a series of snaps of herself on set and showed off her hair and makeup for the Amazon Prime show.
In the first selfie, the Bad Guy hitmaker had fake blood smeared across her face and what appeared to be a big cut under her eye. She stared menacingly into the camera while sporting a blonde wig.
Another picture saw Billie smiling for the camera, despite being covered in the fake injuries.
The final picture was a picture taken outside her green room with a sign that read: "Do not Enter, Eva Green Room!"
Billie simply captioned the post: "eva."
Her fans have been going wild for the post and are already in love with her character, after the show debuted on Friday.
"I don’t even want therapy if it’s not from eva," one fan joked. Another said: "ICONIC."
A third fan commented: "IM SO PROUD," while another praised the makeup departing, writing: "Why does this look so real tho."
Swarm is a horror thriller exploring the themes of extreme fandom.
The show tells the story of Dre (Dominique Fishback), who goes on a murder spree set off by her obsession with Beyonce-esque pop star Ni’Jah.
The seven-part series, which Glover co-created with Janine Nabers, launched on Prime Video on March 17.
While the show is fictional. Billie's creepy character was inspired by the real-life NXIVM cult.
"There is a cult that existed in the world that was very prominent during that time," Janine told the Hollywood Reporter.
"And that is the kind of true-crime element to that episode. And I think that when people think of the idea of artists or celebrities, there is this idea of thinking about the cult of Taylor Swift, or the cult of The Beatles or whatever.
"What we were really interested in was just seeing someone who worships at the altar of ‘something,’ and [exploring] this idea of what is the cult of the mind."
Swarm is Billie's first scripted role, although she has previously appeared in documentaries and voiced herself in an episode of The Simpsons.
Her fans were not disappointed after watching her acting debut and took to social media to share their thoughts.
Commenting on a series of pictures Billie shared with her co-stars on Instagram, one fan wrote: "You f***ing killed it, u are a star."
Another said: "U slayed in this series fr," while a third fan penned: "You deserve an Oscar, emmys AND EVERYTHING."
"Horror movies next pleaseeee," someone else begged.
