What is Olivia Cooke’s ethnicity?

Family background and early life in Oldham

• Olivia Kate Cooke was born on 27 December 1993 in Oldham, Greater Manchester, England (Wikipedia).
• She is an English actress by nationality and descent (Wikipedia).
• Her father, John Cooke, worked as a police officer, and her mother, Lindsy (née Wild), was a sales representative. She has a younger sister named Eleanor. (Spanish Wikipedia, Wikipedia (Spanish) — medium confidence)
• She grew up in Oldham, a former textile town, and began acting in local amateur theatre at age eight (TV Guide).

The implication: Cooke’s ethnicity is white English, rooted in the North West of England. Her early environment — a working-class family in a mill town — shaped her grounded, unpretentious public persona.

Who is Olivia Cooke in a relationship with?

Current relationship status

Cooke has not publicly confirmed a romantic partner in recent years. Her relationship status is private, and she does not share personal details about a partner on social media or in interviews.

Past known relationships

She has been linked to a few co-stars in the past, but no relationship has been officially confirmed. The most notable public connection was with musician and actor Evan Peters: Biography, Relationships, and Net Worth (2025), her co-star in Bates Motel, though neither party has ever confirmed the nature of their relationship.

The trade-off: public curiosity about her private life remains high, but Cooke deliberately keeps that boundary intact. For fans, the lack of confirmation means any claims about a current partner should be treated as speculation.

Why did Olivia Cooke shave her head?

Role preparation for Slow Horses

Cooke shaved her head for the role of Sidonie “Sid” Baker in the Apple TV+ series Slow Horses (Wikipedia). Her character is a young MI5 analyst who operates undercover, and the shaved head was part of the character’s gritty, no-nonsense appearance.

Character context: Sidonie “Sid” Baker

In Slow Horses, Sid is a sharp, tenacious spy assigned to Slough House, the dumping ground for MI5’s misfits. The physical transformation — including the shaved head — helped Cooke embody the character’s intensity and vulnerability.

Why this matters: The decision to shave her head demonstrates Cooke’s commitment to physical authenticity. It’s a move that actors often reserve for career-defining roles, and it helped elevate her profile in the spy genre.

What movies and TV shows has Olivia Cooke been in?

Recent television: House of the Dragon and Slow Horses

• House of the Dragon (2022–present) — plays Alicent Hightower, the queen of the Targaryen dynasty (The Movie Database).
• Slow Horses (2022–present) — plays Emma Lacey / Sidonie Baker (TV Guide).
• Bates Motel (2013–2017) — played Emma Decody, a love interest of the protagonist (Amazon Prime Video).

Major film: Ready Player One

In 2018, she played Art3mis, the virtual-reality love interest, in Steven Spielberg’s Ready Player One (The Movie Database). The role required extensive motion-capture work and physical stamina, drawing on her ballet and gymnastics training.

Early career and breakout roles

• Ouija (2014) — horror film.
• Me and Earl and the Dying Girl (2015) — critical indie hit.
• Thoroughbreds (2017) — dark psychological thriller.
• Sound of Metal (2019) — drama about hearing loss, co-starring Riz Ahmed.
• Television debut in the BBC miniseries Blackout (2012) (TV Guide).

The pattern: Cooke built a career on genre-spanning projects — horror, thriller, period drama, sci-fi — but each role demands a distinct physicality she credits to her early dance training.

Is Olivia Cooke LGBTQ?

Public statements on sexuality

Cooke has never publicly labeled her sexual orientation. She has portrayed LGBTQ characters on screen — most notably in Thoroughbreds and House of the Dragon (where her character’s relationships are ambiguous) — but has not made a personal statement about her own identity.

The catch: audiences often assume an actor’s identity mirrors their roles, but Cooke has not confirmed or denied any speculation. Until she chooses to speak on the matter, her sexuality remains a private matter.

Timeline

• 1993 — Born on 27 December in Oldham, England (Wikipedia).
• 2012 — Acting debut in the comedy series Vivienne Vyle and the short film The Last Day (TV Guide).
