Billie Eilish is set to make her acting debut in Donald Glover’s highly-anticipated horror series, Swarm, which will premiere its entire first season on Friday.

In a trailer for the psychological drama, the Bad Guy singer, 21, portrays a menacing therapist that manipulates her patients into dangerous behaviors through hypnosis.

While seated across the table from a woman, named Dre (Dominique Fishback), who is obsessed with a fictional pop star, the Ocean Eyes crooner snaps her finger and asks: ‘Tell me something you regret.’

Dre, who initially said her name was Kayla before revealing her true identity, recalled seeing milk spilled on the carpet.

‘What color was the milk?’ Eilish’s character asks in a soft tone, to which Dre admits ‘it was red’ like blood.

‘Did you hurt someone?’ the seven-time Grammy winner then asked in a breathy whisper.

The rest of the 30-second preview is filled with chaos, including other characters crawling across the floor and a police officer in the woods.

Through the Beyoncé-Inspired show Dre becomes increasingly violent as she also navigates a trauma involving her sister, Marissa (Chloe Bailey).

The rest of the cast includes Damson Idris, Bryron Bowers, Kiersey Clemons, Paris Jackson, Rickey Thompson, Rory Culkin and X Mayo.

When asked in 2021 what it would take her to star in a film or TV show, Eilish said: ‘If I fall in love with something, I would love to act in it.’

‘It would only have to be the right thing because I’m not an actor and I’m not… It’s not my calling, but I’ve always loved acting,’ the Happier Than Ever hitmaker told The Hollywood Reporter.

She continued: ‘I loved acting as a kid. I would have to really, really feel a connection and have a moment of just, I don’t know, love for it.’

While this would mark her first time acting professionally, her brother and frequent collaborator, Finneas, has appeared in shows like Modern Family, Glee and Bad Teacher.

Their mother, Maggie Baird, is a retired theater troupe teacher, who acted in Life Inside Out, Seinfeld, Bones, The X-Files and more.

On Twitter, fans of Eilish were quick to point out that her latest role could get her one step closer to become an EGOT winner.

Last year, after taking home the Academy Award for Best Original Song at the Oscars for her song, No Time to Die, she became just two trophies away from the coveted title, that only 18 other stars have achieved.

The only other awards she needs to need now are a Tony and Emmy Award.

‘Billie Eilish acting career STARTS NOW WE WON,’ one excited fan tweeted

Thrilling: Another raved that the trailer looked ‘unreal’

Previously unannounced: Some were impressed her role was kept under wraps for so long

‘Haunting & hypnotic, you’ll willingly follow her into the deepest & darkest parts of the world,’ one social media user praised
